The Luth-AR Modular Chassis Assembly (MCA-22) is a precision rifle stock system purpose-built for shooters who want to transform their Ruger 10/22 into a tack-driving platform for competition and recreational hunting. This chassis replaces your factory stock with a fully adjustable, ergonomic system that turns a budget-friendly rimfire into something that feels and shoots like a purpose-built competition rifle. If you run a standard or bull-barrel 10/22 receiver and want real precision without the price tag of a centerfire platform, this is your answer.
Built from glass-filled nylon and aluminum with steel components, the MCA-22 delivers rugged durability at a weight of just 2.09 lbs—light enough that it won't bog down your 10/22 during a full day at the range or in the field. The chassis is 100% ambidextrous, so lefties and righties get the same level of control and comfort. Everything adjusts to fit your body: length of pull runs from 11.25 to 15.75 inches in .75-inch increments, the cheek piece clicks up and down 2 inches (+1 to −1 from bore center), and the aggressive texturing on the grip and front strap keeps your hands locked in place whether you're shooting prone, from a rest, or offhand.
The modular design keeps things practical. The foregrip accepts standard M-LOK accessories, includes a pre-drilled sling stud locator (10-32 tap required), and ships with a removable taper barrel insert to accommodate bull barrels without fuss. Up top, the goose-neck pistol grip sports an ambidextrous palm swell for natural hand position, and the stock accepts two locations for GrovTec threaded quick-detach cup inserts. Available in Black or Flat Dark Earth, it collapses to 27 inches and extends to 30.75 inches—compact enough for hunting brush country, long enough for a comfortable shooting position. This is a chassis-only system; you'll supply the receiver, trigger group, and barrel.
Whether you're chasing sub-MOA groups at a rimfire precision match or setting up a lightweight hunting rifle that punches above its weight, the Luth-AR MCA-22 gives you the adjustability and control of a custom rifle at a fraction of the cost.
| Weight | 2.09 lbs |
| Overall Length (Collapsed) | 27 inches |
| Overall Length (Full Extension) | 30.75 inches |
| Width | 1.790 inches |
| Length of Pull (Collapsed) | 11.25 inches |
| Length of Pull (Extended) | 15.75 inches |
| LOP Adjustment Increment | .75 inch |
| Cheek Rise Range | 2 inches total (+1 to −1 from bore center) |
| Cheek Rise Adjustment Increment | .090 inch |
| Materials | Glass-filled nylon, 6061 aluminum, steel |
| Finish Options | Black, Flat Dark Earth |
| Compatibility | Ruger 10/22 standard and bull-barrel receivers (non-takedown) |
The MCA-22 is designed for Ruger 10/22 standard and bull-barrel receivers, but it is NOT compatible with takedown models or receivers with a rear tang. It also does not fit bolt-action .22s. If you have a standard fixed-receiver 10/22, you're good to go.
Yes. The MCA-22 is a chassis-only system. You'll need to provide the Ruger 10/22 receiver, trigger group, and barrel. Once you have those components, assembly is straightforward.
Absolutely. Length of pull adjusts from 11.25 to 15.75 inches in .75-inch increments to fit different body sizes. The cheek piece is click-adjustable and rises up to 2 inches total (+1 to −1 from bore center), so you can dial in your sight picture quickly and comfortably.
The chassis weighs 2.09 lbs, making it a lightweight upgrade that won't bog down your rifle. The design is intended to improve handling and precision without adding unnecessary heft.
