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 stout polymer body that's fit with a hardened, QPQ salt bath nitrided steel plate insert. The steel plate is heavily textured for aggressive contact with your shooting rest. It is also slightly curved for optimized contact on uneven surfaces, giving you the ability to pivot your firearm while maintaining contact and control. Compatible with octagonal M-LOK Handguards. Made in the USA.
