According to Ohio Ordnance Works, the OOW240P is a belt-fed, air-cooled, crew-served machine gun system capable of sustained and accurate suppressive fire while using a shorter and lighter barrel, M4 style collapsible stock, and removable lightweight bipod which can be replaced with a foregrip due to the new bottom Picatinny rail. Note that the barrel comes with dimpling, which reduces weight while increasing heat dissipation, plus it looks very Spec Ops.

It also features a Select Fire Trigger Assembly, which allows the operator to switch between semi-automatic and fully automatic modes of fire. The gun is gas-operated, and it fires from an open bolt.
