The Luth-Ar Modular Chassis Assembly (MCA-22) in Flat Dark Earth transforms a Ruger 10/22 into a precision-capable rifle built for both recreational shooting and competition use. This chassis system pairs a lightweight, ergonomic design with genuine adjustability—letting you dial in your rifle to fit your body and your shooting style, not the other way around. If you run a standard or bull-barrel 10/22, the MCA-22 gives you a modern platform without the premium price tag of a factory takedown or custom build.
Built from high-strength glass-filled nylon and aluminum with strategic steel reinforcement, the chassis keeps weight down while maintaining rigidity. The ambidextrous goose-neck grip features an integral palm swell and aggressive texturing on both the grip panels and front strap, giving you solid purchase whether you're shooting left or right-handed. A click-adjustable cheek piece lets you dial vertical rise up to 1 inch above or below bore center, critical for getting a repeatable sight picture with red dots, scopes, or irons. Length of pull adjusts from 11.25 to 15.75 inches in 0.75-inch increments, accommodating shooters of different statures and gear configurations.
The foregrip integrates M-LOK slots on the bottom and both sides, so mounting lights, rails, or other accessories is straightforward. A removable, tapered barrel insert handles bull-barrel models without modification. The butt stock includes two QD cup insert locations for quick-detach slings, and the front bottom features a pre-drilled sling stud locator (10-32 tap required). This is a chassis-only system—you provide the Ruger 10/22-style receiver and barrel—but installation is straightforward and requires no gunsmithing.
The FDE finish blends into hunting and outdoor environments while resisting corrosion. Overall length ranges from 27 inches collapsed to 30.75 inches fully extended, keeping the rifle compact yet manageable in the field or on the line.
