The NGSSCSR-BLK uses a compact, MDT-compatible aluminum chassis built for precision and modularity - a concealable, chassis-style “stock” with adjustable length of pull, an adjustable cheekpiece, and mounting interfaces for monopods, sling mounts and other accessories. Unlike traditional polymer stocks, this aluminum chassis provides a rigid, bedding-free platform that holds the Surgeon 591 action tightly for repeatable accuracy, while its shortened footprint and optional folding or low-profile fittings keep the rifle maneuverable and easier to transport or conceal. The chassis also accepts standard chassis accessories (MDT pattern) so you can tailor ergonomics, balance and shooting setup - from low-profile tactical builds to fully accessorized precision rigs.
