Fits all AR-15 lower receivers with Mil-Spec .250" diameter front pivot and rear takedown pin holes. The enhanced takedown pin and pivot pin are CNC machined from Grade 5 titanium bars. Low profile pin heads are ambidextrous safety compatible. An added tip length noticeably aids in starting/pushing the pins out from the left side of the receiver. A cone shaped recess at both pin tips prevents accidental bullet or tool slip. Kit includes two KNS hardened stainless steel detents, two 17-7 nickel plated stainless steel pin springs and a high-strength neodymium magnet for hassle free installation. The titanium pins are 50% lighter than a Mil-Spec pin set. MADE IN THE U.S.A.
NOTE: The enhanced pivot pin is NOT compatible with the AX556 receiver due to the receiver's proprietary design (enhanced takedown pin will work). May not be compatible with the KNS anti-walk sear pin without modificaiton to the sear pin.
