Battle Arms Development Enhanced Pin Set AR-15/M16/M4 Titanium Natural

The Battle Arms Development Enhanced Pin Set is a precision drop-in upgrade for standard AR-pattern lowers, machined from solid Grade 5 Titanium bar stock and finished in a raw, uncoated Titanium Natural appearance. Each pin is CNC-machined to mil-spec tolerances for a clean, no-slop fit on a stripped lower during assembly or as a direct swap on a built rifle.

Designed as a direct replacement for factory pivot and takedown pins, the set fits all standard AR-15, M16, and M4 lower receivers that use the mil-spec .250 in. diameter pin holes. Battle Arms Development engineered this enhanced set to be roughly 50% lighter than the standard mil-spec pin set, trimming reciprocating mass at both ends of the lower without sacrificing the strength expected from a duty-grade pin set.

The kit ships complete with the front pivot pin, rear takedown pin, two KNS detents, and two springs - everything required for a full installation. Designed and manufactured in the USA, the Enhanced Pin Set is a clean, lightweight refresh for any mil-spec AR build and a simple way to drop weight from the receiver interface.
