METALFORM - AR-15 Magazine 9mm 10rd Steel Black

I bought 2 metalform10 round mags for my cmmg dedicated 9 mm ar lower and upper. Both have worked flawless with about 200 through each mag.

I have had this American spirit arms 9mm conversion for some time now. The modified uzi mag that came with was so so, I even bought some uzi mags and modified them myself on my mill. Couldn't get 100% feeding corrected. contacted ASR for a fix they just blew me off. Saw this mag on sale bought it. PROBLEM FIXED SENT 10 MAGs FULL DOWN RANGE NOT ONE FEEDING OR EXTRACTION PROB.I just wished I had bought them sooner. I would give it a 10 star if poss, it has fixed my 9mm conversion........Going to buy more even if not on sale that's how good they are. fit and finish great Ar just looks funny with a short mag.

The mags are solid and well made. But I'm only giving 4 stars because the first mag I got would barely go in and out of the magwell. My other 9mm mags from Brownells worked fine so I didn't figure the magwell was out of spec. Fortunately they exchanged them no problem and the second one worked great. So check the mags as soon as you get them I guess is the lesson learned. Love the shorter 10 round mags in my pistol. Much easier to pack and store.

I had to enlarge the hole that the magazine catch uses to lock the mag in place. After that it worked fine.Never had to do that with Colt mags.

Where do i start. Bought two of them they both have the same failures. Both had incorrect feed lip angels , both followers had angels to steep at the face of the feed lips. The combination of these issues caused the mags to fail miserably in all three 9mm carbines i tested them in. To add insult to injury the mags in all three guns which all have different manufactured mag blocks would stick in the mag well and needed to be yanked out . Metal form really dropped the ball on this one. I seriously recommend that you drop this product Brownells.
