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. The Push Button Quick Detach Sling Swivel has a matte phosphate finish for corrosion resistance and signature reduction. It is compatible with all common quick detach (QD Swivel) sockets found on some buttstocks, forends, rails, or aftermarket socket adapters.This model has a 1.25 loop size.
