Cross Armory CRQP Quick Pins Rear Takedown Pin AR-15/M4 Mil-Spec Black 7075-T6 Aluminum

The Cross Armory Quick Pins rear takedown pin kit is a drop-in upgrade that replaces the standard rear takedown pin on any Mil-Spec AR-15 or M4 lower receiver. Instead of pushing out a tiny detent and chasing a spring across the bench, the Quick Pins design opens with a simple pinch of the finger and automatically locks back into place when you close the receiver - making upper-to-lower separation and re-latching fast and one-handed.

Each pin is CNC machined from solid 7075-T6 aircraft aluminum for an excellent strength-to-weight ratio, then finished in a subdued black anodized coating that pairs cleanly with factory and custom AR lowers. The kit is dimensioned to Mil-Spec tolerances so it installs in place of the factory rear takedown pin without modification.

Quick Pins are a popular customization for competition shooters who break down their rifles often, range users who want easier cleaning access, and builders who simply want their AR-15 or M4 to function the way the takedown pins were meant to. The CRQP kit is the rear pin only and is intended for Mil-Spec platform lowers.
