Description The Magpul Barricade Stop is a rugged hand stop that allows the shooter to brace their firearm off barricades or field expedient shooting rests to create a stable platform for more accurate shots. The Barricade Stop is constructed of a polymer body thatâs fit with a hardened, QPQ-treated steel plate insert. The steel plate is heavily textured for aggressive contact with your shooting rest. Itâs also slightly curved for optimized contact on uneven surfaces, giving you the ability to pivot your firearm while maintaining contact and control.
