Specs:
M&p-15
-carbine length gas system, 16" barrel running with a standard a2 buffer spring and buffer. (magpul PRS)
-m16 bolt assembly
-Stock everything else.
About every 5 or so rounds, when the gun is chambering a new round it will do this.
The round is severly bent at the bottleneck, and there will be several large gouges on the casing. It may take 2 rounds to do this, or sometimes i can get through 15 before it happens. Ive tried 8 diffrent GI- style magazines of all make.
Heres the strange thing... I tried one of my sig 556 magazines in it, and it functions flawlessly. But ONLY the sig 556 magazines. Standard GI, Pmags and H&k stainless mags all fail to function. The gun functioned flawlessly before its recent makover.
Any ideas guys?
