50 BEOWULF AR15 Barrel 

The 50 Beowulf (12.7x42mm) is the largest caliber available for the AR15 and it has the take-down power for deer, moose, and black bear inside 150 yards - think of it as a hotrod, 1800 fps, 12-guage slug for your AR15. For close quarters combat, the 400-600 grain projectile has tremendous stopping- and penetrating-power. The rebated cartridge rim is compatible with the 6.5 Grendel (Type 2) bolt carrier group, and the cartridge length and diameter are compatible with large bore, single stack AR15 (450 Bushmaster) magazines.

AR15Parts.com barrels are sourced from top US manufacturers including Ballistic Advantage, Shaw Barrels, Swan Machine, Wilson Arms, Wilson Combat, ZRO Delta, and others.
