First poly mag I used / tried was the Canadian issued mag. Traded a few with the troops from Cold Lake deployed to 1st Gulf war. It would “fuzz” up for a better word in the abrasive sand of the middle east. Increased the size of the dang thing in a mag well. Only GI metal mag I trusted or carried was made in Parsons Kansas. I kept cases of those in my gear lockers and always took spares along if possible. My 1911A1 Mags were and still are wilson rogers 8 round stainless.
The PMAG’s are all I have in my gear now as a civilian and a reserve sheriff deputy.
MagPul didn’t donate to the socialist rats is my opinion why their excellent product is being banned by the bean countin REMF’s.
I smell Surefire at play here as well. not sure as to the reliability of the new 60 & 100 round magazines they sell so won’t bad mouth em yet the more new and improved that shows up in a grunts gear the less happy his NCO’s are .....
Testing , trial and error are for the range and shoot house. Not combat.
Is there a certain model of Magpul in 5.56 that is better than the others? I see them selling for about $15 at Cheaper Than Dirt. I had a plastic 30 round Thermold that came with my first AR and it caused my gun to jam at least once every time I used that magazine so I swore off plastics. I replaced the magazine with NHMTG’s and haven’t had a problem since.
