The .50 Beowulf is a rifle big-bore cartridge developed by Alexander Arms for use in a modified AR-15 rifle. Why does it belong in your AR collection?
First and foremost, it is based on your standard AR-15 platform. The .50 Beowulf is compatible with standard AR-15 upper and lower receivers, handguards, buffer systems and small parts. The only difference is the barrel and your BCG, not counting the magazine, which it takes 6.5 Grendel Type II Bolt Face. It is entirely possible to slap a complete .50 Beowulf upper receiver onto a standard AR-15 lower receiver and maintain total functionality. A standard AR-15 buffer and buffer spring do not even need to be replaced to effectively handle the .50 Beowulf’s increased recoil, as the Beowulf cartridge was designed to work specifically with standard lower receiver components.
The .50 Beowulf cartridge adds an extraordinary “wow” factor. Rugged, precise and with brute power to spare, the beastly cartridge of .50 Beowulf undoubtedly can harvest every big game animal in North America. The rifle produces a distinct thumping muzzle blast that literally makes shooters feel the hair on their head move. Surprisingly, although the .50-caliber cartridge produces a whopping 2,400 foot-pounds of muzzle energy, it felt recoil is comparable to a 12-gauge shotgun with 2-3/4-inch bird shot. Given its ability to excel at a variety of objectives from hunting to home defense, it’s quite clear the .50 Beowulf is a solid example of a reliable all-purpose tool that can go anywhere and do anything.
