Informed by years of overseas use during contingency events the BCM Mod 3 Stock is the newest refinement of the baseline M4 accessory. A minimalist snag free component, the BCM Mod 3 Stock has been shaved down to 6.4 oz. slick with an improved double-walled (H-Beam) construction to ensure reliability and durability during use. Two friction fit M3 marksman risers, approximately .5" and .8", have been designed to interface with the Mod 3. These risers can be mounted in six positions, and can be oriented either forward or reverse to provide the end user a unique flexibility in configuring their weapon system. When employed with the M3 optional marksman riser, the BCM Mod 3 Stock enables a consistent cheek weld when running electro-optics and low powered variable optics set up for passive night vision employment or close-quarter battle.Features :No Riser IncludedTool-Less Install/RemovalRemovable Solid Diamond Textured Non-Slip ButtpadHorizontal and Vertical Web Sling Attachment Points
