In the upcoming July 2014 issue of RIFLE FIREPOWER, author Bryce M. Towsley discusses some of the big-bore AR ammo alternatives to the ubiquitous .308 Winchester/7.62mm NATO. Towsley writes, “Last issue we covered the cartridges chambered in AR-15-style rifles. This column deals with cartridges chambered in its bigger brother. The trouble is that I am not sure what to call it. While Colt technically owns the rights to ‘AR-15,’ the term has become generic to describe the rifle. When you say an AR-15-type rifle, everybody knows what you mean. ArmaLite owns the trademark to the AR-10. It calls its gun the AR-10, but the rest of the makers had to get cre- ative if they want to avoid trouble.
“DPMS calls its big-bore AR rifles LRs, as in LR-308, LR-338, etc. Even the new Gen II DPMS guns have the LR designation. Rock River Arms calls its own the LAR-8, and with JP Enterprises, it’s the LRP07. Ruger calls its rifle the SR-762. The list goes on, and to avoid confusion, a lot of shooters just call them .308/7.62mm ARs. But, as we are about to find out, that’s not correct either, as there are plenty of other cartridge options beyond the .308 Winchester/7.62mm NATO.
“So, I think I’ll just invent my own term: AR-Large, or AR-L for short. It should keep me and this magazine out of trouble, and you will all know what I am referring to as a rifle platform. Most of the new gun-makers entering the field are following the DPMS concept, and that has become the standard, more or less. Magazines and some other parts will interchange, whereas the AR-10 and some others use a different magazine and most parts will not interchange with the DPMS-style guns. Confused? Me too.”
