OOW240P Patrol

Ohio Ordnance Works’ Latest Entry Into The General Purpose Machine Gun (GPMG) Field Is Our New Lightweight OOW240P (Patrol) Model.

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.

The OOW240P also features our patented Select Fire Trigger Assembly which allows the operator to switch between semi-automatic and fully automatic modes of fire as a standard accessory. OOW also manufactures a Select Fire Trigger Assembly for our 249 light machine gun.

MIL-STD 1913 Picatinny Rails on the top cover and at the 3,6, and 9 o’clock positions of the forend allow for the mounting of numerous accessories including laser devices, lights, night vision, thermal, day optics, and various foregrips and bipods.

The new shorter barrel features dimpling which reduces weight while increasing heat dissipation with no loss of strength or durability. The barrels are available with either single or three position gas regulators and are fully compatible with existing Blank Fire Adaptors.

OOW specializes in arsenal level manufacturing, repairing, rebuilding and servicing of small arms and crew served weapon systems. With our experience, extremely competitive pricing, and rapid delivery, OOW is an obvious choice for your crew served weapon requirements.
