MDT LSS-22 Gen 3 Chassis System for Ruger American Rimfire – Black (115064BLK)

Upgrade your Ruger American Rimfire with the MDT LSS Gen 3 Chassis System (115064BLK) — a premium, tactical-grade chassis designed to dramatically improve accuracy, ergonomics, and overall performance. Engineered by Modular Driven Technologies (MDT), one of the most trusted names in precision rifle chassis systems, the LSS Gen 3 is purpose-built for shooters who demand more from their rimfire platform.

The LSS Gen 3 chassis replaces your factory stock with a rigid aluminum bedding block and AR-compatible pistol grip interface, accepting standard AR-style pistol grips for a fully customizable fit. The folding stock mechanism and adjustable length-of-pull and cheek riser compatibility allow shooters to dial in the perfect ergonomic setup for any position — bench, prone, or field. The result is a more consistent cheek weld, improved trigger control, and tighter groups downrange.

Constructed from high-strength aluminum with a durable matte black anodized finish, this right-hand chassis is built to withstand the demands of competitive shooting, small game hunting, and range training alike. The ARCA/Picatinny-compatible forend provides ample attachment points for bipods, lights, and accessories, making it as versatile as it is precise.

Whether you’re a competitive rimfire shooter, a serious plinker, or a hunter looking to maximize every shot, the MDT LSS Gen 3 is the definitive chassis upgrade for your Ruger American Rimfire.
