So, What’s Up With 7.62X39 MM In AR Rifles?

 

 

 

 

” There’s a modern trend going on with a retro cartridge these days. Evidence of it can be found in the SIG Sauer 556R (rumored to have been developed at the behest of a specific high-speed military customer) and then there is the brand new CMMG MK47 Mutant. Essentially these are Western SIG or AR-based rifles or carbines chambered for the 7.62×39 mm cartridge that do not come with the limitations of the AK-47 platform—but do employ the AK magazine. And, for military operators, there is less of training curve (which is somewhat important for guys who train all the time). I was once told regarding such guns, “There are times and places you just don’t want to leave Lake City 5.56 on the deck.” That is but one explanation as to why we are seeing more and more contemporary AR-style rifles chambered for the Soviet M43 cartridge.”

 

 

 

” Originally developed for use on the Germans during World War II (December 1943), the cartridge we know as the 7.62×39 mm cartridge was first used by the Red Army in the Simonov SKS carbine in 1945 and then became almost synonymous with the world’s most produced firearm, the Avtomat Kalashnikova or AK-47. If being 71 years old does not qualify a cartridge for “retro” I’m not sure what would.

  But it turns out the 7.62×39 mm has many advantages for civilians as well. First of all, with a bullet designed for expansion, it is a pretty good short- to medium-range hunting cartridge. You doubt me? Ballistically, it delivers similar performance to the venerable .30-30 Win. No one doubts the hunting credentials of that cartridge. And the 7.62×39 mm offers intermediate .30-cal. power out of the basic AR platform, on the cheap.”

 

 

 

 

” Bill Ruger recognized the cartridge’s potential when he introduced his Mini-30 carbine back in 1987. And, of course, Colt started chambering its Sporter in 7.62×39 mm in 1992 (although neither of those used an AK magazine), and other makers have followed suit since. ArmaLite, Bushmaster, Del Ton, Doublestar, DPMS, MGI Olympic and Rock River have offered complete rifles and/or uppers for the AR platform in 7.62×39 mm. No doubt there are others; likely with more on the way. “
