18" 50 BEOWULF Parkerized Bull Barrel AR15 Upper Receiver with 15" Rail and Thread Protector
The 50 Beowulf (12.7x42) was developed to achieve maximum stopping power on the AR15 platform and the 300-400 grain bullets found in typical commercial ammunition pack a mean punch. The 50 Beowulf cartridge is designed to be compatible with the popular 7.62x39 bolt, making it an easy extension for your AR15 arsenal. There are few rounds more effective or devastating at close range than the 50 Beowulf.
