In the upcoming November/December 2014 issue of TACTICAL WEAPONS, author John Higgs rounds up some of the best semi-auto and bolt-action 300 Blackout rifles on the market today.
Higgs writes, “The wars fought in Afghanistan and Iraq since 9/11 have shown the need for a cartridge more effective than the standard 5.56mm NATO round. Military planners wanted a .30-caliber bullet similar to the Soviet 7.62x39mm AK-47 cartridge with the same or better performance. The challenge was to design a cartridge that would be more effective at greater distances and defeat barricades more efficiently, minimize the effects of crosswinds over longer ranges and feed 30 rounds from a standard AR magazine. The tactical demands of battle also required a cartridge that could be loaded to subsonic velocities yet still function reliably and accurately in short-barreled rifles with suppressors.
“Developed by Advanced Armament Corporation (AAC), the 300 AAC Black- out, or 300 BLK, can be fired from a standard 5.56mm AR simply by changing out the barrel. The dimensions of the 300 BLK cartridge are the same as the .300 Whisper, which preceded it. The difference is that the 300 BLK was approved by SAAMI. Here are some of the latest 300 BLK rifles available today.
“Based in Milan, Ill., Lewis Machine & Tool (LMT) started producing high-grade firearms for the U.S. military, law enforcement and government agencies in 1980 and has since expanded into the American civilian market as well as British military units. The CQB105300 offers a 10.5-inch, chrome-lined barrel chambered for the .300 Whisper, rock-solid iron sights and a collapsible SOPMOD stock. The 16-inch-barelled variant (CQB 16-300) has an MSRP of $2,100.15.
“The AAC MPW is a short-barreled rifle that is also available with a 16-inch barrel for customers who choose not to file the additional NFA paperwork. A Geissele trigger and Magpul’s stock and pistol grip are standard. The 1-in-7-inch-twist barrel is nitride-coated for extreme corrosion resistance, which leads to a longer barrel life. The MPW also comes with a free-floating Knight’s Armament URX 3.1 Rail forend with short Picatinny rails for mounting accessories.”
