MCA™-22 Modular 10/22 Chassis Assembly

MCA™‑22 Modular 10/22® Chassis Assembly

The MCA™‑22 Modular Chassis is a fully adjustable, precision‑engineered upgrade for the Ruger® 10/22® rifle platform. Designed to give shooters a custom‑fit feel and repeatable shooting position, the MCA‑22 allows fine‑tuning of cheek height, length of pull, and butt plate position - all critical for achieving consistent accuracy shot after shot.

Compatible with both standard tapered barrels and .920" bull barrels, the MCA‑22 includes a removable barrel‑channel insert so you can tailor the chassis to your specific build. Constructed from high‑strength glass‑filled nylon, 6061 aluminum, and steel, this chassis delivers durability, stability, and ergonomic comfort for a wide range of shooters. Its fully ambidextrous design, adjustable cheek rest, and goose‑neck pistol grip make it a versatile upgrade for hunting, target shooting, and precision rimfire builds.

Chassis only - user must provide action and barrel.
