At just 3.8 lbs., the O.I.P. shoots surprisingly well thanks to the intentionally balanced design and the Thumper brake.
Battle Arms’ generation 2 O.I.P. weighs just 3.8 pounds, and it shoots really well. It’s small and light and low profile. Weight was cut by using titanium and making cutouts, but nothing is exposed that will allow the action to get dirty. “Ounces Is Pounds” is a true saying, and Battle Arms has done a lot of work to find all the ounces that can be spared to make this gun as light as possible.
Carbon fiber grip. Ounces is pounds.
Do you really need a full-length Picatinny rail? Ounces is pounds.
Machined carbon fiber handguard. Ounces is pounds.
Titanium parts: bolt catch, gas block, muzzle brake, bolt carrier, grip screw, pivot and takedown pins, stock screw.
Do you really need a T-shaped charging handle? Nah, a J-shape works fine. Scallops on the upper. Ounces is pounds.
But it’s not just lightweight. They’ve developed the titanium “Thumper” muzzle brake to keep the barrel flat, and you’ll see in the video that even at full auto it does a terrific job. Battle Arms’ O.I.P. Gen 2 is in production, but they completely sold out the first run so you’ll have to wait a few weeks for yours to arrive. MSRP is $3,299.
The Thumper has two ports on top set at an angle on the corners, and it works well.
