This model HK snap is a steel model (vs. the die cast zinc) and is perfect for gun slings, shoulder straps, tactical military/ law enforcement purposes, or if you just want to spruce up your backpack without adding bulk. The HK snap comes to us in a gun metal flat black; which has a low reflection rate, or silver; which may be powder coated to any color at your discretion. Flat Black snaps are not available for powder coating. These snaps are intended for use with 1 1/4" webbing though in house testing has determined that 1 1/2" webbing will work for snaps sewn in place.
