What are the specs on the standard Browning Automatic WWII support rifle?

The barrel length is about 24 in, or 610 mm. It chambers a .30-06 Springfield cartridge, a .303 British, or a 7x57mm Mauser. The rate of fire is 500 to 650 rounds per minute, depending on which model you are talking about. The sights are a rear leaf and front post setup. It can be fitted with a bipod, an external pistol grib, Cutts compensator and even a bayonet, even though those were pretty rare. I hope this helped!
