I'm dusting off the cobwebs from my competition AR and decided to do some function tests. Prior to this, I have not run PMAGs through this rifle and it just worked.
First function test, had failed to feed with all magazines and my reloads. I had two steel and on PMAG. After the RO lent me some CLP, it started working. Took it home and gave it a thorough cleaning, used Mobile 1 for lube.
Second function test. I took this rifle and a new M4gery build with just PMAGs. Four PMAGs and all of them failed to feed right, even with Winchester 5.56 ammunition, through the competition rifle. I even had double-feeds I tried the same mags and ammunition in my new build and it had no problems with the magazines.
Ejection both times with the competition rifle was fine. I've put maybe 800 rounds through it. During the cleaning I shot Brake Cleaner through the gas tube, it came out the other end just fine. I'm testing this weekend with steel mags to see if it still likes those. Anyone else have problems with PMAGs on a build?
The lower in question is a Spikes, with a CMMG LPK, Ergo F93 Pro stock with included receiver extension, standard carbine buffer and spring.
