    Battle Arms Development Enhanced Pin Set (BAD-EPS) for the AR15 / M16 / M4 style rifles.

    The BAD-EPS features the following improvements and features:

    • Precision Swiss CNC machined.

    • AR15 / M16 / M4 Compatible - Fits all AR15/M16/M4 lower receivers with mil-spec .250in diameter front pivot and rear take-down pin holes.

    • Patent Pending Pivot Pin & Take-down Pin Head Designs - Greatly improved gripping surface and pull strength without the use of oversize heads.

    • Low Profile Pin Heads - Low drag and never in the way. Lower profile than mil-spec pin heads.

    • Ambidextrous Safety Compatible - The Enhanced Take down Pin (BAD-ETP) head design does not obstruct the use of the right side ambidextrous safety selector lever.

    • Extended Pin Tips (+0.030in over mil-spec) - Added tip length noticeably aids in starting/pushing the pins out from the left side of the receiver, without undue protrusion.

    • Bullet Tip Guide - Cone shaped recess at both pin tips prevent accidental bullet or tool slip and reduced the chance of scratching/damaging of the receiver.

    BAD-EPS comes with:

    • (1) Enhanced Takedown Pin

    • (1) Enhanced Pivot Pin

    • (2) KNS hardened stainless steel detents

    • (2) 17-7 nickel plated stainless steel pin springs.

    1. AX556 owners please note that the EPP (Enhanced Pivot Pin) is incompatible with the AX556 receiver due to the receiver's proprietary design. The ETP (Enhanced Take-down Pin) will work as designed.

    2. Depending on your M16 receiver, may not be compatible with the KNS anti-walk sear pin without modification to the KNS anti-walk sear pin.
