As author Todd Burgreen writes in the December 2013 issue of Special Weapons for Military & Police, in 2001 Alexander Arms introduced the .50 Beowulf cartridge, which utilizes a rebated rim sized to fit within an AR bolt head with dimensions similar to a 7.62x39mm bolt face. “The .50 Beowulf operates with bullets weighing between 300 and 400 grains and which travel at 1,800 to 1,900 fps depending on barrel length and bullet weight. The .50 Beowulf was specifically designed by Alexander Arms to generate unprecedented stopping power at short to moderate ranges out of the AR.” Luckily, Burgreen was able to get his hands on Alexander’s Entry rifle to test the .50 Beowulf round.

The Entry rifle features a 16.5-inch, chrome-moly barrel with a 1-in-20-inch twist rate and capped with a Petter Pot muzzle brake. The brake uses five simple rows of holes arranged in a helical pattern to redirect muzzle gas and reduce recoil. The entire rifle weighs about 8 pounds unloaded and has a fixed stock.
