The lightweight 16-in/50 Mark 7 was designed to resolve this conflict. These guns were 50 calibers long, 50 times their 16-inch (406 mm) bore diameter with barrels 66.7 ft (20.3 m) long, from chamber to muzzle. Each gun weighed about 239,000 lb (108 t) without the breech, and 267,900 lb (121.5 t) with the breech. [1]

These dimensions allow the 300 AAC Blackout to be used in existing magazines designed for M16 or AR-15 rifles. Because the rim of the ...
Loaded ammunition in the 300 BLK caliber can be purchased as light as 100 gr, with the 125 gr class of bullets proving to be popular when shooting at higher velocities. However, to use a bullet that has a weight near 125 gr at supersonic velocities, the .277 caliber has a much more ideal shape for stability and accuracy (longer and slimmer ...
The larger diameter, shorter 6 mm cartridge is optimized for these shorter barrel lengths, and would perform less efficiently from rifle-length barrels. The round's muzzle energy is 831 ft⋅lbf (1,127 J) versus 792 ft⋅lbf (1,074 J) for a 5.56 mm bullet, again from the same 10" standard barrel.
The weapon is suppressed and it can be made even quieter by using heavy subsonic .300 Blackout ammunition. Kevin Brittingham, the founder of AAC, wanted to design a weapon which had the ease of use of an AR-15, but the portability of an MP5.
