Battle Arms Development OIP Gen 3 Features The Battle Arms Development OIP Gen 3 is built to shoot full-powered mil-spec 5.56 NATO ammunition while weighing just 4.6 lbs an achievement made possible by a patented buffer system working alongside a lightweight titanium bolt carrier finished in ArmorTi for corrosion and wear resistance. A custom mid-length gas system is balanced specifically against a titanium Thumper compensator tuning the rifle s recoil impulse and muzzle rise for a 10.5 pencil profile barrel. The 7075-T6 billet aluminum receivers finished in Combat Gray are not simply skeletonized and hollowed out but carefully engineered with structural consideration keeping the rifle rigid despite the extensive weight savings. A titanium billet CNC machined bolt catch adds further weight reduction without sacrificing durability. Gen 3 brings a user-configurable M-LOK carbon fiber handguard and a carbon fiber pistol grip that weighs barely one ounce both aimed squarely at shaving further ounces off an already ultralight platform. A Rack charging handle and Picatinny rail top the upper while a Vert Rapid Deployment collapsible synthetic buttstock keeps the rear of the rifle compact for this SBR configuration. Ambidextrous controls including the safety lever make the OIP Gen 3 usable for both right and left-handed shooters without compromise. For sale at GrabAGun the OIP Gen 3 suits shooters seeking a true survival carbine combining full-power 5.56 performance with an exceptionally lightweight compact SBR build.
