BATTLEARMS OIP 003 Gen 3 — Lightweight Ultralight AR-15 Carbine / 5.56

The BATTLEARMS OIP 003 Gen 3 is the lightest production ultralight survival carbine built without compromise. At only 4.6 pounds and chambered for full-power Mil-Spec 5.56 NATO / .223 Wylde, the OIP® blends extreme weight savings with battle-proven strength and reliability. Years of R&D and multiple U.S. patents produced a purpose-designed system where nearly every component is custom Battle Arms Development — not a parts gun.

Key technologies include the patented OIP buffer system, a lightweight titanium BCG finished in ArmorTi™, a custom mid-length gas system, and a titanium THUMPER™ compensator. Gen 3 upgrades add a user-configurable carbon-fiber M-LOK handguard, carbon-fiber pistol grip, a titanium billet bolt catch, and the RACK® charging handle — all while maintaining exceptional controllability and minimal recoil.

Why choose the OIP 003 Gen 3

• Ultra-light but rugged: 4.6 lb system engineered for survival and carry without sacrificing durability.
