The Blue Force Gear Push Button Sling Swivel was designed to be stronger and lighter than the common Push Button QD Swivels. The smaller swivel body and push button reduces weight while minimizing the chance of accidentally disengaging the swivel. A larger gauge sling loop gives increased strength and durability. It is compatible with all common quick detach (QD Swivel) sockets found on some buttstocks, forends, rails or aftermarket socket adapters. Fits Vickers Combat Applications Slings 1" Sling. Made in the USA.
