  • Lightweight, easy-to-install polymer stock is the strongest in its class.
  • Rattle-free, snag-free design. No sharp edges prevent the tangling of the rifle with the shooter’s sling, MOLLE gear, or other kit.
  • Two ambidextrous sling mounting options, including QD swivel sockets.
  • Modular. Six parts and one screw allow for the modular adaption of future configurations.
  • Integrated rubber buttpad for secure shoulder placement and increased durability.
  • The 6-position receiver extension is machined from impact-extruded 7075-T6 aluminum alloy for improved strength and durability.
  • Comes with a BCM carbine spring and a 3.8 oz H1 buffer.

Made in the USA.

Will an H1 buffer work with my setup?
Short answer, maybe… There are tons of factors that go into buffer tuning and selection. H1 will work for most setups, but it may not be the ideal weight for yours. We recommend doing some research to find what buffer weight will best suit your setup.
