Mdt Lss-xl Gen2 Fixed R700 Sa

The MDT LSS-XL Gen2 Fixed R700 SA is a modern chassis system designed to transform standard Remington 700 short-action bolt rifles into ergonomic, modular precision platforms. Built for law enforcement marksmen, military precision shooters, and serious civilian hunters, this chassis bridges the gap between traditional bolt-action simplicity and modern tactical rifle flexibility. The R700 SA designation indicates compatibility with Remington 700 short-action receivers, the industry standard for precision rifle builds.

The LSS-XL Gen2 is an extended-length variant of MDT's proven LSS chassis, incorporating aluminum construction for structural rigidity while maintaining a lightweight profile at 2.44 lbs. Its 30-inch overall length provides enhanced foregrip control and accessory rail real estate. The chassis features full AR-15 ergonomic compatibility—accept standard AR buttstocks, grip modules, and rail systems—allowing rapid ergonomic customization to fit different shooters and mission requirements. The fixed configuration eliminates collapsible stock complexity, delivering superior cheek weld consistency and bedding stability critical for precision applications where sub-MOA accuracy is non-negotiable.

This chassis excels for shooters running precision Remington 700 SA builds in competitive long-range competitions, police sniper programs, or designated marksman roles where modular ergonomics and repeatable accuracy matter. Installation requires receiver bedding into the aluminum chassis—a straightforward process within reach of gunsmiths and experienced builders. The 5.5-inch width accommodates standard tactical chest rigs and shooting bags, while the integrated accessory mounting system supports optics, bipods, and ancillary gear without additional adapters. Verify your specific Remington 700 short-action model before purchase to ensure receiver fit.
