Battle Arms Development Enhanced Pin Set (BAD-EPS) for the AR15 / M16 / M4 style rifles.   The set consists of the Enhanced Take-down Pin (BAD-ETP) and Enhanced Pivot Pin (BAD-EPP). Precision Swiss CNC machined from round stock steel bars, the BAD-ETP & BAD-EPP are case hardened and finished in mil-spec black manganese phosphate.

The BAD-EPS features the following improvements and features:

• 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.
• Patent Pending EZ Guide Channel & Magnetic Assist Install - Easy, hassle free magnet assisted installation of the EPP (Enhanced Pivot Pin). No more lost detents and springs.
• Weight: .49oz

Each BAD-EPS comes with (1) BAD-ETP, (1) BAD-EPP, (2) KNS hardened stainless steel detents, (2) 17-7 nickel plated stainless steel pin springs, and (1) high-strength neodymium magnet for hassle free magnet assisted installation of the Enhanced Pivot Pin (BAD-EPP).

Proudly designed and manufactured in the U.S.A.

Notes:

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. 3. Neodymium magnet is not a toy. Use only for the installation of the EPP. Keep out of reach of children.
