The good folks over at Ohio Ordnance Works posted a teaser on social media this week that would lead fans to believe they are working on an NFA-compliant M2 .50 cal. 

Posting an image of six unfinished side plates like those seen on the M2 Browning heavy machine gun on social media Monday, the company said simply "Sooo, there might be a new product coming soon." The top plate is engraved "M-2 SLR .50 cal Self Loading Rifle" along with OOW's Chardon, Ohio, roll mark and a serial number that starts in the 85,000 range.

The M2 Browning has been a staple of the U.S. military in one form or another since the 1920s with Anniston Army Depot recently coming across one that had been in the field for 90 years without needing repair. More than 3 million have been built for the U.S. and overseas allies by dozens of firms and arsenals.

The very definition of a heavy machine gun, the "Ma Deuce" weighs 84 pounds by itself, exclusive of its mount, but can deliver 450 rounds per minute out to 2,000 meters as long as the ammo and barrel hold out. (Photo: Chris Eger/

Ohio Ordnance, probably best known on the consumer market for its semi-auto version of the M1918 BAR light machine gun, the 1918A3-SLR, speaks MG fluently.

They produce both M2HBs and M2HB QCBs for gov/mil customers, so the M-2 SLR will likely be well done, if expensive. Still, man caves and all that. (Photos: OOW)
