Designed in partnership with Unity Tactical , the SB22 Fixed Kit is a lightweight, modular chassis for the Ruger 22 Charger and its clones. Able to accept M1913-compatible braces and stocks, the SB22 Fixed Kit is the key component to the perfect pack gun. The forend of the chassis features M-LOK compatible mounting slots at the 3, 6, and 9 o clock positions, as well as a Picatinny/M1913 compatible bridge cover for maximum compatibility with optics and other accessories. At the rear of the chassis, an integrated ambidextrous steel QD socket allows for a variety of sling attachment options. The Fixed Kit is compatible with most standard AR-15 pistol grips and includes a Reptilia CQG Grip. Our Fixed Kit chassis is made from a durable, lightweight reinforced polymer for maximum durability without adding bulk. Additionally, an aerospace-grade aluminum insert ensures a secure fit with Ruger 22 Charger receivers, both OEM and aftermarket. As with all SB Tactical products, the SB22 Fixed Kit is proudly made in the USA.
