From Commander Zero we have a link to a story written for SWAT Magazine by James Yeager of Tactical Response where he chronicles “what happens to a bunch of ARs, AKs and various pistols when you subject them to 12 very intense days and nearly a quarter million rounds of ammunition.”
The end result? Everything breaks, some gear is better than others but nothing is invincible. (story)
Is the information presented useful for the average defender of hearth and home? I say yes. Even though the likelyhood of you winding up in a situation like this training class is for is very small. Knowing what works best and what to avoid can offer some peace of mind. Personally, if I buy any more AR magazines I’ll be buying P-Mags.
