Due to the size of the .300 Win. Mag. cartridge, pairing with an AR-15 or AR-10 receiver is impossible, so NEMO (New Evolution Military Ordnance) Arms took to the drawing board to create a rifle that houses qualities of the AR platform, and did so around a magnum cartridge that’s been a favorite among long-range shooters and hunters. The NEMO Arms Omen is a self-loading rifle that feeds from its detachable-box magazine and runs off of an adjustable, suppressor-ready direct-gas-impingement-system. To learn more about the company and its rifles, watch this week's NRA Gun of the Week video hosted by American Rifleman's Kelly Young, and check out nemoarms.com
