The Ruger 10/22 Charger ships from the factory as a pistol-configuration variant of a sixty-year-old rifle. It wears a polymer chassis molded around a die-cast receiver, a ten-inch heavy barrel threaded 1/2x28, a factory folding brace, and a single BX-15 magazine. The Charger is intended as a platform — Ruger sells it that way, and the aftermarket has organized itself around that intention for two decades. Roughly twelve hundred dollars at retail. Around four pounds at the scale.

What it is from the factory is a starting point. The chassis is plastic. The brace is a compromise. The barrel is twice the length it needs to be for the use case this rifle eventually became. The factory configuration is not the rifle this article is about. It is the rifle this article is about, before someone with a lathe and a CNC decided what to keep and what to throw away.

What stayed. The receiver, bolt, and trigger group are the only factory parts in the finished rifle. Photography: IMG88.

The Charger is the 10/22 action sold without a buttstock. Ruger markets it as a pistol. Functionally, it's identical to the rifle: same receiver, same trigger group, same bolt, same magazine. What changes is the legal category, which changes the build path.

For a builder targeting a short-barreled rifle, the Charger is the correct starting point. Cutting down a 16-inch 10/22 rifle to a five-inch barrel produces a rifle below the federal 16-inch threshold, which makes it an SBR, a National Firearms Act item, regulated, requiring a tax stamp and ATF approval. Starting with a pistol and adding a buttstock produces the same end state through different paperwork. Either way, the registered configuration is an SBR. The Charger path is the more direct one: the barrel is already short, the receiver is already configured for a pistol-style installation, and the host doesn't have to be modified out of a longer configuration first.

A short-barreled rifle, in U.S. federal terms, is generally a rifle with a barrel under sixteen inches, or made from a rifle, with an overall length under twenty-six inches. The appeal is mechanical: compact, easier to move with, easier to store, easier to shoulder quickly. A 16-inch rifle with a suppressor on the muzzle becomes a long, front-heavy package. A five-inch barrel with the same suppressor keeps the overall length close to a standard rifle's, and the balance closer to the shoulder.

Suppressors changed the math on short barrels. A 16-inch rifle with a five-inch suppressor is a 21-inch package. A five-inch rifle with a five-inch suppressor is a ten-inch package, folded eight or nine inches when the stock is collapsed. The same suppressor; very different rifle.

The owner of this build started with a new factory Ruger 10/22 Charger. Plastic chassis. Threaded barrel. Factory folding brace. Everything except the receiver, the trigger group, and the bolt eventually went in a parts bin.

Two rifles, two disciplines. The 5" Duerksen SBR (top) and the owner's customized 16" Carbon Competition (bottom). Photography: IMG88.

66 Tactical, Oklahoma City. A precision-rimfire match on a Saturday night. The owner of this build had brought a Ruger 10/22 Carbon Competition from Ruger's Custom Shop, sixteen-inch carbon-sleeved barrel, target chassis, factory-tuned trigger. By any standard catalog metric, the most rifle a 10/22 buyer could buy without leaving Ruger's product line.

It was an excellent rifle. It was also the second-most-interesting 10/22 on the line that night.

The rifle that displaced it was Jared Duerksen's personal build. A 10/22 Charger in a factory Grey Birch LaChassis - finish as shipped, no Cerakote - with an integrally-suppressed barrel and a red dot on top. No magnifier. No color work. The chassis as it left the factory, the barrel and suppressor as one piece. The whole package weighed less than the suppressor on a centerfire rifle. Folded, it disappeared.

The owner shot the Carbon Competition through the stages, watched Duerksen run the SBR through the same stages, asked questions afterward, and commissioned a build before leaving the property: built to the owner's own spec, not a mirror of Duerksen's rifle.

The sixteen-inch stayed in rotation. It still gets shot often, but it gets a different treatment: an Arken EP5 5-25x rides on top, and it's run slow and steady, the way a bolt action gets run. The SBR is the closer complement to the owner's 9mm PCC: a different style of shooting built around fast transitions and target acquisition. Two rifles, two disciplines, neither one replacing the other.

What changed between rifles wasn't accuracy. The Carbon Competition was, and is, a precise rifle. What changed was the experience: the package, the balance, the way the rifle moves between targets, the way it shoulders and unshoulders. The SBR was faster. Quieter. Lighter. More fun, in a way that mattered.

This is a familiar story in the modern rifle market. A serious shooter discovers that the next step in a category isn't a more accurate factory rifle, it's a builder who will throw away most of what the factory did. The catalog is the floor. The build is the ceiling.

Duerksen Designs operates out of Oklahoma. The shop's capability list reads short and obvious: CNC mill, four-axis mill, lathe, laser engraver, optic milling, barrel threading, custom one-off parts, stippling, action tuning, full custom builds. The work that comes out of it doesn't.

Asked why he keeps building 10/22s when the platform has been beaten on for sixty years, Duerksen's answer was simple. The rifles are fun. They're cheap to shoot. Kids can shoot them. Grandkids can shoot them. The aftermarket is enormous, but, as he put it, "there's ten million ways to build a 10/22, but everyone's got the same thing." The work, for him, is the part where the build stops being everyone's.

The 10/22 SBR count to date: roughly fifteen builds, with eight or nine of those in the Grey Birch LaChassis specifically. The chassis has become his default for the platform. Asked why, the answer was straight: he likes them, the machining is clean, they have good lines, and the silhouette doesn't read blocky the way other rimfire chassis can.

What separates a Duerksen build from a parts-box assembly is the work that doesn't have a catalog SKU. The Charger that became this rifle didn't have an off-the-shelf four-inch forend for the LaChassis when Duerksen needed one, so he machined one. The barrel was chopped to length, threaded, sleeved in carbon fiber, and Cerakoted. The chassis was fully stripped before refinishing, burnt bronze on the body, graphite black on accents, then reassembled. The Strike Industries folding stock was integrated where the factory brace had been.

Total time, start to finish: two weeks. That's fast for a build of this depth. Two weeks is what it takes a one-man shop with the right machines to execute a build that, at a less-equipped shop, would sit for months waiting on outsourced barrel work and outsourced finishing.

Asked what makes a build worth doing, Duerksen's answer was the same answer good builders give in any discipline: the challenge. "I thrive on challenges. I get bored with mundane just bolting stuff together. If it's different or weird or challenging, that's what drives me."

He won't claim to be the fastest or the cheapest. He won't claim either of those things because he isn't trying to be. He's trying to ship work he'd be proud of, on the timeline that takes, at the price the materials cost.

Duerksen Designs operates out of a shop in Oklahoma — a CNC mill, a four-axis mill, a lathe, a laser engraver, and the kind of organized clutter that means the tooling gets used. The builds leave that shop one at a time. Fifteen 10/22 SBRs in, the man's defaults are clear: a Grey Birch LaChassis, a carbon-sleeved barrel, a HUXWRX suppressor, and a finish system that he won't ship until it reads right under shop light. The work is what he's proud of. The catalog is not.

Grey Birch MFG builds modular chassis systems for the Ruger 10/22, CZ 457, and Tikka T1X rimfire platforms. The LaChassis 10/22 is their flagship: a modular aluminum chassis designed to cradle the barreled action from two anchor points and present an M-Lok forend, a Picatinny stock mount, and folding-stock capability.

Duerksen specced the LaChassis DLX for this build. The DLX variant is the folding-stock factory configuration: extended M-Lok forend, adjustability for length-of-pull and cheek weld, and a Picatinny stock interface that accepts mil-spec mounts. The chassis-to-receiver fit is tight enough that no set-screw tension is required to seat the action; the receiver drops into the chassis and the barrel block locks it forward.

What the chassis does, mechanically, is solve the two problems the factory 10/22 platform has when pushed. The first is barrel rigidity at full extension: a factory 10/22 barrel cantilevers off the receiver alone, which is fine for plinking and starts to matter on precision work. The LaChassis adds a second anchor point at the forend, which keeps the barrel rigid through the firing cycle. The second problem is shoulder-to-action consistency under stress. The folding stock collapses for transport and locks in the fixed position for shooting, with no positional drift between sessions.

What the chassis does aesthetically is the harder thing to explain in a parts list. Most rimfire chassis on the market look blocky, engineering-first machining with hard transitions and sharp shoulders. The LaChassis carries the same modularity in a profile that flows. Lines move front to back instead of stacking. The forend reads as part of the rifle, not a tube clamped on.

For a build that was going to live in burnt bronze with graphite black accents, that mattered. Cerakote does what Cerakote does: it covers metal. If the metal underneath is blocky, the bronze amplifies it. The LaChassis carries the finish.

The barrel is the most modified piece on the rifle. The factory Ruger Charger ships with a ten-inch threaded barrel. Duerksen chopped it down to five inches, short enough that the suppressor mounts almost flush to the receiver area when paired with the LaChassis forend.

The threading is 1/2x28, the standard rimfire pattern, which makes the barrel direct-thread compatible with effectively every rimfire suppressor on the market. The HUXWRX Flow 22 Ti is the suppressor that gets installed on this rifle most often, but the threading isn't dedicated to it. A direct-thread interface means the suppressor threads onto the muzzle with no quick-disconnect mount, no booster, no maintenance assembly between the barrel and the can.

After threading, the barrel was sleeved in carbon fiber. Carbon sleeving is a weight-reduction technique borrowed from precision-rifle builds: a thinner-walled steel barrel section is wrapped in carbon fiber under tension, which yields a barrel that's both lighter and stiffer than an equivalent all-steel section. On a five-inch barrel the absolute weight savings are modest, but the visual reads cleaner: one tube instead of a stepped profile. The barrel and suppressor become a single visual element. The eye doesn't catch the transition.

The carbon sleeve is finished in graphite black Cerakote, which is the accent color across the rest of the rifle. The chassis is burnt bronze. The accents, barrel sleeve, bolt, charging handle, small hardware, are graphite black. The barrel reads as accent, not as a separate component. It belongs to the finish system.

The HUXWRX Flow 22 Ti is the suppressor at the muzzle. Lightweight, full-auto rated, titanium-printed, 5.5 inches long, 3.9 ounces empty, direct-thread 1/2x28. The defining feature is the flow-through architecture: gas vents forward through the suppressor rather than getting trapped, baffled, and redirected back toward the shooter. The result is less blowback at the shooter's face, less toxic gas in the action, and reduced wear on the bolt and recoil components.

For a 10/22 Charger SBR running standard ammunition, the math gets unusual.

A five-inch barrel doesn't burn powder the way a 16-inch barrel does. Most .22 LR is loaded for full burn out of a 16-to-22-inch barrel; running it through five inches leaves powder unburned. The muzzle velocity drops by twenty to thirty percent depending on the load. Standard CCI Standard Velocity 40-grain leaves a rifle-length barrel at roughly 1,050 to 1,100 feet per second. Through five inches, it leaves the muzzle at 950 to 970. The speed of sound at sea level is 1,125. The math, in this rifle, is automatic.

The implication is that standard ammunition becomes subsonic in this rifle without buying subsonic-specific loads. The supersonic crack that ordinarily accompanies a .22 LR rifle shot is gone. With the suppressor installed, the loudest sound the rifle makes is the bolt cycling.

That isn't a slight noise reduction. That's the rifle crossing a threshold. With hearing protection, the shot is a non-event. Without hearing protection, it's hearing-safe within reasonable proximity, a useful property for a backyard rifle, a training rifle, or a rifle a child or new shooter can use without flinching from the report. The cartridge becomes friendlier than it has any right to be.

The quiet has one practical consequence the owner didn't expect. He tried running split-times and timing drills on the SBR the way he does on his 9mm PCC, and the shot timer couldn't score it. The report is so soft that the timer's microphone physically won't pick up the shot. There's no acoustic event loud enough for it to register as a shot. A rifle this quiet defeats the tool built to measure how fast you shoot it.

The suppressor is direct-thread, with no quick-disconnect mount, no booster, no maintenance assembly. It threads onto the muzzle and stays there until it's removed for cleaning. HUXWRX recommends a 500-round cleaning interval, or when the suppressor weighs five ounces, whichever comes first. The new-from-the-box weight is 3.9 ounces; the maintenance threshold is a one-ounce gain.

Holosun SCRS-GR-MRS green-reticle rifle sight with the HM3X three-power magnifier. The serial-number band reads SCRS-GR-2 on this unit. Photography: IMG88.

The optic is a Holosun SCRS-GR-MRS, the Solar Charging Rifle Sight in the green-reticle, multi-reticle variant. Solar-augmented battery that keeps itself topped off in ambient light, a 2-MOA dot paired with a 65-MOA ring that can be toggled independently or stacked together, and a low-profile 7075-aluminum housing on the 509T mounting footprint. The SCRS is one of Holosun's newer entries into the small-rifle optic category, and on a 10/22 SBR it's almost too much optic, which is the right amount, because the rifle's primary mission is short-range fast acquisition, and its secondary mission is precision at distance.

Forward of the SCRS, on a flip-to-side mount, sits the Holosun HM3X three-power magnifier. The HM3X stays out of the optical path when the rifle is being used fast and swings into line when the rifle is being used slow. The combination is a fast green-dot setup that becomes a 3x scope at the flick of a thumb lever. For a cartridge that rewards precision, the .22 LR's appeal is the surgical entry and exit at small targets across modest distance, the magnifier opens up shooting that pure dot acquisition can't.

The configuration is unusual on a five-inch rimfire SBR mostly because most rimfire SBR use cases don't need a magnifier. Backyard plinking, training, fast competition stages, suppressor demonstration, all of these are dot work. The magnifier earns its place by extending the rifle's role into the precision shooting that the cartridge is genuinely good at. A .22 LR through a 3x at fifty yards is a different rifle than a .22 LR through a dot at twenty.

The green reticle is its own decision. Green sits closer to the human eye's peak sensitivity than red, at roughly 520 to 555 nanometers, where the eye is most efficient at distinguishing brightness against varied backgrounds. In bright sunlight against a foliage background, a green dot stays sharper than a red one without having to be turned up. The trade is power draw, which on a solar-augmented sight matters less than on a battery-only optic. Most shooters never see the difference. The shooters who do prefer green.

Also on the chassis, M-Lok mounted on the forend: a Votatu M9L-G Mini. A 550-lumen LED light combined with a 5-milliwatt Class IIIA green laser at 520 nanometers, the same wavelength range the SCRS is illuminating. Low-profile direct-mount to M-Lok, magnetic USB rechargeable, hard-anodized aluminum housing. The light is a working illuminator at any reasonable indoor distance. The green laser is a sighting aid for low-light use, or for a shooter who can't get behind the optic.

The green-on-green pairing isn't an accident. The rifle has two ways to put a point on a target, the reticle in the optic, and the laser on the forend, and they're the same color. Set the magnifier aside and the shooter sees a green dot inside the sight. Activate the laser and a green point appears on the target. Same wavelength, different mechanism, one visual language. The rifle's pointing systems agree with each other.

Below the chassis, on the M-Lok forend, an HKP M-Lok vertical foregrip. HK Parts makes the foregrip with the same locking mechanism used on the H&K factory MP5K grip: a knob at the base of the grip engages and disengages the M-Lok mount with a quarter turn. No tools required for installation or removal. The vertical grip gives the rifle a different shooting position than the standard horizontal-hand hold on the forend, useful when the rifle is being used at a stable bench, less critical when it's being shouldered fast. It's another option, ready to use, not in the way.

The magazine seated in the rifle is a Ruger BX-25. Ruger's twenty-five-round factory magazine for the 10/22 platform, designed as an extended-capacity replacement for the standard ten-round rotary. On a 10/22 build that gets passed around at the range, the BX-25 is the right call: twice the time between reloads, factory-original parts compatibility, and a profile that complements the SBR silhouette better than the flush rotary does. The flush mag still works in the rifle; the BX-25 is what's in it.

Cerakote is a ceramic-polymer coating sprayed and cured over metal. It's the modern standard for firearm finishing: durable, available in dozens of colors, applied in a curing oven at controlled temperature. Most production rifles wear it. Custom rifles wear it. The question on a custom build isn't whether to Cerakote, it's how to use color.

Duerksen's choice was a two-color system. Burnt bronze as the dominant color, on the chassis body. Graphite black as the accent color, on the barrel sleeve, the bolt, the charging handle, and small hardware. Two colors, intentional placement, every piece refinished in the same shop on the same day.

Why two colors and not one: a single-color rifle reads flat. A two-color rifle, finished intentionally, reads built. The eye registers the bronze as the rifle and the graphite as the working parts. The visual hierarchy matches the mechanical one: what moves is darker, what holds is lighter. The bronze is the body. The graphite is the motion.

Why burnt bronze and not the more common Cerakote desert tans or grays: the owner wanted a finish that wasn't generic. Bronze sits warm without sitting orange. It reads metal without reading military. On the LaChassis silhouette, which flows rather than stacks, the bronze reads as a finish chosen for the rifle rather than picked from a list. Most rifles in burnt bronze at a range are tan rifles with an unfortunate name. This one is bronze the way a bronze sculpture is bronze.

Doing the work in-house, on the same day, by the same shop, matters more than most buyers realize. Cerakote color matching across two shops is a real problem: the same color name from two different applicators can come out two visibly different shades depending on cure time, spray distance, and base prep. Duerksen did every piece on this build. The bronze is the same bronze across the whole rifle. The graphite is the same graphite.

The rifle weighs just over four pounds. That's suppressed, with the optic and magnifier and light/laser and vertical grip and a loaded magazine. For context, a Glock 17 with a loaded magazine weighs about a pound and a half. Most centerfire AR-15s in fighting configuration weigh seven to eight pounds. This rifle, fully kitted, weighs less than a sandwich shop's burrito.

That weight is what changes the experience.

The rifle shoulders one-handed. It folds to under eleven inches. It runs subsonic ammunition out of standard supersonic boxes. The optic is solar-augmented and the dot stays on the target through the recoil cycle because there essentially isn't one. The bolt cycles, the case ejects, the next round chambers, the dot resettles. The whole sequence is quieter than a stapler.

The rifle on the line. Range day, 12 April. Photography: IMG88.

The recurring pattern on a range day: serious shooters, people whose primary discipline is centerfire precision rifle, large-bore hunting, or competition-grade pistol, pick the SBR up off the bench and shoot it longer than they intended to. The cartridge cost is negligible. The recoil is negligible. The noise, in this rifle specifically, is negligible. What's left is the mechanics of getting hits, divorced from the cost and ceremony of the larger rifles in the rack.

That's the experience the owner kept describing in different words: the rifle is fun in a way that doesn't require justifying itself. A child can shoot it. A first-time shooter can shoot it. A shooter who's been doing this for thirty years picks it up, looks at the target, and reaches for it again on the next stage. The .22 LR has been the entry-level rimfire for a century. The 10/22 has been the entry-level rifle platform for six decades. This particular configuration takes both of those legacies and pushes them into a corner of the rifle world they haven't traditionally lived in: a precision-capable, hearing-safe, fast-handling, suppressed mini-carbine that costs about a quarter of what a full-house bolt-action rimfire chassis rifle does.

What changes from rifle to rifle is the experience around the cartridge. The owner's other 10/22 is a Ruger Custom Shop product, the highest of the catalog line, and an excellent rifle by every measure that ammunition and groups can confirm. The SBR isn't more accurate at the bench, and it didn't replace the sixteen-inch. It's a different rifle for a different job. By every measure that matters to a shooter who's holding it, it's more rifle. Faster. Quieter. Lighter. More compact. More interesting to look at. More interesting to use.
