JP Microfit Takedown Pin

Cure what ails your ill-fitting receiver set or just spruce them up with high-quality new look.

This set of MicroFit™ Takedown Pins includes both the front pivot pin and rear takedown pin for a small-frame receiver set. Oversized pins will remove much if not all of the slack in a loose receiver set while undersized pins will help with easier takedown of overly tight receivers like those with excess finish buildup.

To gauge the pin fit for your third-party receivers, you can use standard takedown pins or gauge pins. For the AR-15, Mil-spec pins are roughly equivalent to a .248 gauge pin. Oversized and undersized MicroFit™ Pins are offset slightly over .001 larger or smaller.
