Battle Arms Development Enhanced Pin Set AR-15/M16/M4 Aluminum 7075-T6 Flat Dark Earth

The Battle Arms Development Enhanced Pin Set (EPS) is a matched pair of upgraded lower-receiver pins that makes stripping down an AR-pattern rifle faster and easier. The set combines the Enhanced Pivot Pin (EPP) and the Enhanced Takedown Pin (ETP) into one drop-in package, with patent-pending head designs that let the user push the pins out by hand without reaching for a pin punch.

Both pins are precision Swiss CNC machined from 7075-T6 aluminum for a strong, lightweight upgrade over the standard steel pins. The set is finished in a low-glare Flat Dark Earth anodize to match FDE receivers, handguards, and furniture.

The EPS is built to mil-spec tolerances and fits all standard AR-15, M16, and M4 lower receivers that use the standard .250" diameter front pivot and rear takedown pin geometry. The pin heads are sized to clear standard upper-receiver takedown lugs, so installation is a direct swap with no fitting required.

A practical drop-in upgrade for any AR build, the Battle Arms Development Enhanced Pin Set delivers a cleaner look, lighter carry weight, and the convenience of tool-free pin removal in a single affordable package.
