Brownells 75th Anniversary - A Shooting Heritage

Quick-Release For Fast Takedown Without Tools

Pushbutton-release pin replaces the factory pivot screw and nut at the front of the receiver to enable quick, separation of the SIG 556 upper and lower receivers with finger pressure only. Three, spring-loaded detent balls hold the pin in place and prevent wear or binding in the pivot hole or receiver hole when removed. Black oxide finish matches the receiver; stainless steel internal parts resist corrosion.
