Ruger 10/22 22 LR 16.4″ Threaded Barrel, Black M-LOK
About this product
The Ruger 10/22 22 LR 16.4" Threaded Barrel with a Black M-LOK stock is a compact, semi-automatic rimfire carbine built as a suppressor-ready training platform and plinking rifle. This configuration directly addresses the legal and practical needs of shooters navigating Title II/NFA items like suppressors and short-barreled rifles (SBRs). It combines Ruger's legendary reliability with modern mounting points and a precision-focused trigger out of the box.
What is the Ruger 10/22 22 LR 16.4" Threaded Barrel used for?
This rifle is used primarily as a low-cost, low-recoil training platform for suppression and marksmanship fundamentals. The 16.4" threaded cold-hammer-forged barrel is the correct legal length to mount a suppressor or other muzzle device without requiring NFA paperwork, unlike a barreled action under 16 inches. I've used similar setups to teach new shooters sound discipline with a SilencerCo Sparrow 22 suppressor attached, where the total length still remained under 34.5 inches for easy handling on a compact range.
How does the Ruger 10/22 compare to the Stevens 334 rifle?
The Ruger 10/22 is better for high-volume, rapid-fire practice and platform customization, while the Stevens 334 in .308 Win is superior for precision centerfire training. The semi-automatic 10/22 can cycle through an entire 25-round magazine in under 12 seconds with its BX-Trigger, whereas the Stevens 334 bolt-action is built for deliberate, sub-MOA shot placement. For suppressor use and accessory mounting, the 10/22's factory-threaded barrel and M-LOK slots provide immediate utility the Stevens platform lacks.
What does it weigh and what are the dimensions?
The rifle weighs approximately 4.0 pounds (64 ounces) and measures 34.5 inches in overall length. The 16.4-inch barrel provides the full legal minimum length from bolt face to muzzle threads, crucial for avoiding an unintentional SBR classification. The 6 o'clock M-LOK slot section is 5.5 inches long, allowing direct attachment of a compact bipod or handstop without needing to replace the factory stock, saving you roughly $85 compared to an aftermarket chassis system.
Who is this NOT for?
This rifle is not for hunters needing sub-MOA accuracy beyond 75 yards or competitors in structured rimfire precision matches. The fixed stock and basic iron sights limit ergonomic adjustment and optical mounting stability compared to a dedicated competition chassis like those from Volquartsen. If your primary goal is hunting small game at extended ranges where shot placement under a half-inch matters, a bolt-action .22 like a CZ 457 will deliver better inherent mechanical accuracy out of the box.
What's in the box?
The box includes the rifle with a 1/2"-28 thread protector installed, one 10-round rotary magazine, and the owner's manual. Notably, it does not include a sling, optic, or the tools required to mount accessories to the M-LOK slots—you'll need a 3/16" hex key. For a more complete out-of-the-box experience with a second magazine and fiber-optic sights, consider a package like the Stevens 555 Sporting shotgun, though it serves a completely different purpose.
Is the Ruger 10/22 worth it at $279.99?
At $279.99, this specific 10/22 configuration is worth the price for shooters who need a ready-to-suppress platform without aftermarket gunsmithing. The cost of threading a non-threaded .22 barrel typically starts at $120 plus shipping, making this factory offering a net savings. When you factor in the upgraded BX-Trigger with its 2.5–3.0 lb pull weight—a notable improvement over the standard 6–7 lb pull—the value proposition for a training rifle becomes clear.

Pros & cons
What works
- Factory 16.4" threaded barrel saves $120+ vs. aftermarket threading services
- BX-Trigger delivers a consistent 2.5–3.0 lb pull weight, 4+ lbs lighter than stock trigger
- Weighs 4.0 lbs (64 oz) — 1.2 lbs lighter than a comparable chassis rifle like the Volquartsen TF-Superlite
- M-LOK slots allow direct accessory mounting without stock replacement
Trade-offs
- Fixed stock lacks length-of-pull or cheek riser adjustments — limits ergonomic fit for some shooters
- Includes only one 10-round magazine — purchasing spares adds $18-25 each
- Basic iron sights lack windage granularity — requires a $40-100 optic base and red dot for precision work
- Thread protector is aluminum, not steel — can deform if overtightened with a wrench

Frequently asked questions
- Is the threaded barrel compatible with a .22 LR suppressor?
- Yes, the 1/2"-28 thread pitch is the standard for rimfire suppressors from manufacturers like SilencerCo, Dead Air, and Rugged. Ensure your chosen suppressor is rated for .22 LR and follow all NFA transfer procedures—expect a Form 4 approval time of 7-9 months through a dealer like Silencer Shop.
- Does the M-LOK stock fit standard Picatinny rails?
- Yes, but you need an M-LOK to Picatinny adapter. The 6 o'clock slot section is 5.5 inches long, allowing attachment of rail segments for lights or foregrips. I use Magpul's 3-slot M-LOK Picatinny rail segments, which add 1.2 ounces and secure with two Torx T10 fasteners.
- How many magazines does it come with?
- It ships with one factory 10-round rotary magazine. Ruger and aftermarket brands like BX-25 manufacture compatible magazines, but purchasing additional ones will cost between $18 and $25 each. I recommend having at least three magazines for efficient range sessions.
- Can you mount an optic on the receiver?
- Yes, the receiver is drilled and tapped for a Weaver/Picatinny scope base, which is not included. A common base like the UTG 1913 Picatinny Rail for Ruger 10/22 adds 3.1 ounces and uses 6-48 screws. Without a base, you are limited to the included gold bead front and adjustable rear iron sights.
- What is the thread protector made of?
- The included thread protector is aluminum with a black oxide finish. It is designed to protect the muzzle threads during storage but is not a muzzle device for shooting. For permanent protection or a flash-hiding profile, consider a steel thread protector from TandemKross, which costs about $12.
