R.I.P. One AR-15 Rifle – Another 300 Blackout / .223 Kaboom

By Aaron Spuler | April 23, 2014 |

I’ve read a few stories recently about someone, somewhere, shoving a 300 AAC Blackout cartridge into a .223 / 5.56mm rifle and pulling the trigger – subsequently blowing their gun to bits. Some folks call BS and say it can’t happen as the rifle won’t go into battery and fire.

Well, I’m a believer now, considering a guy 3 lanes down from me blew up his fairly nice looking AR today. In the confusion, I was not able to get the brand of the rifle, but that matters little. Containing 55,000 pounds per square inch of pressure is not in the job description.

    The guys saying it’s bull must not own a 300blk AR because I do and they will definitely chamber in my .223/5.56 AR. Paint or tape your mags guys.

    I have my tan magpul pmags designated as my 300blk magazines. That’s all that I will put in them. My other color pmags are designated as .223/5.56 magazines.
