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 and a textured, QPQ ferritic nitrocarburized steel plate insert for confident contact with your shooting rest. The metal plate is slightly curved for optimized contact on uneven surfaces and provides the ability to pivot your firearm while maintaining contact. It is also removable, allowing it to be replaced after wear. One polymer body, a textured metal insert, and 2 sets of M-LOK hardware are included. Compatible with octagonal M-LOK Handguards. Made in the USA.Specifications and Features:Model: Barricade StopMaterial: PolymerColor: Flat Dark Earth
