Battle Arms Development BAD-EPS Enhanced Pin Set AR-15/M16/M4/AR9 Grade 5 Titanium Black PVD

The Battle Arms Development Enhanced Pin Set is a premium drop-in upgrade for your AR-15, M16, M4 or AR9 platform lower receiver. Each set includes an Enhanced Pivot Pin (EPP) and an Enhanced Takedown Pin (ETP), precision CNC machined from Grade 5 Titanium for roughly 50% lighter weight than a standard mil-spec pin set, finished in a durable Black PVD coating.

The pins are engineered to fit all AR-pattern lowers with the standard mil-spec .250" diameter front pivot and rear takedown pin holes. The Enhanced Pin design features an ambidextrous, snag-free profile that installs without razor blades, pliers or special punches, and ships with two KNS-hardened detents for a secure, repeatable lockup under hard use.

Whether you are building a lightweight competition carbine, refreshing a duty rifle, or simply want the most corrosion-resistant pivot and takedown hardware available for your AR, the BAD-EPS Titanium Enhanced Pin Set delivers the durability, weight savings, and clean aesthetics that serious AR builders expect from Battle Arms Development.
