The B5 Systems Modular Picatinny Stock for Picatinny is a stock that fits Picatinny, offered in Black, Flat Dark Earth, Coyote Brown, Wolf Grey.
The B5 Systems Modular Platform Stock features an integral left-side folding steel hinge, adjustable length of pull, spring-assist cheekpiece, ambidextrous fixed and limited rotation quick disconnect sling mounts, and a nonslip buttpad. Attaches via 1913 Picatinny mount. Constructed of durable composite materials and steel hardware.
The stock sets your length of pull and cheek position, so it has a direct effect on how consistently you can build a position behind the rifle. Collapsible AR-15 stocks slide on to the buffer tube (receiver extension) — check whether your rifle has a mil-spec or commercial diameter tube, as the two are not interchangeable.
