Battle Arms Development’s OIP Gen 2 is on display at their booth, featuring some noticeable changes since its appearance at last year’s Industry Day at the Range. The OIP Gen 2 comes in at 3.8 lbs bare and unloaded, and features a 14.5″, 1:7 twist barrel with a 5.56 NATO chamber, midlength gas system, and a pin and welded Battle Arms Ti THUMPER compensator, bringing the barrel to 16″ in length. Both the pistol grip and forend are constructed of carbon fiber, with weight-reducing lightening cuts, and the later also features M-LOK compatible accessory mounting slots. The receiver set is also aggressively skeletonized, and a majority of the components are made of titanium, including the bolt catch, gas block, bolt carrier, and takedown pins; a fixed aluminum, minimalist receiver extension/stock completes the rifle.
