The Battle Arms Development Enhanced Pin Set (brand part number 100-800-001) swaps the two heaviest small parts on an AR15/M16/M4/AR9 lower for a titanium version of each. The set pairs the Enhanced Takedown Pin (BAD-ETP-Ti) with the Enhanced Pivot Pin (BAD-EPP-Ti), both precision CNC-machined from Grade 5 titanium bar stock and finished in black for this version rather than left in raw titanium. Because titanium is significantly lighter than the steel used in a mil-spec pin set, the pair comes in at roughly half the weight of the factory pins without giving up strength.
