Battle Arms Development produces the Enhanced Takedown and Pivot Pins Set (EPS) for AR15 users who require the best in every single part of their rifles.

The EPS makes disassembly easier than ever. The enlarged pin tips make it a breeze to push the pins through from the left side of the rifle without creating a snag point. The pin heads are knurled around the sides and tapered inward to form a superior gripping surface.

Another useful feature is the presence of cone-shaped dimples on both sides of the takedown pin, which prevent pin punches from sliding off and scratching the receiver during disassembly or reassembly. The EPS is also fully compatible with ambidextrous safety selectors.
