KNS SIG 556 Push Button Pivot Pin

This pin is designed to replace the screw and nut on the front of the receiver. It features KNS Precision's ball detents for easy assembly and a solid locking mechanism. This pin features a black oxide finish to match the receiver, and stainless steel internals for corrosion resistance. This take-down pin has a spring loaded push button. When pushed, the three stainless steel keeper pins retract for easy pin removal. Now you can quickly separate the upper and lower receivers without using an additional tool. Like everything we make, they carry our lifetime warranty.
