About this product

At a listed weight of 4.40 lbs and a 16-inch barrel, the OIP balances low mass with the structural design of 7075-T6 billet receivers. The rifle uses a patented OIP buffer system and a titanium bolt carrier with ArmorTi finish, paired with a mid-length gas system and a titanium compensator. Gen3 upgrades include a user-configurable M-LOK carbon-fiber handguard, a carbon-fiber pistol grip, a titanium billet bolt catch and a RACK charging handle.
