Ammunition Storage Components Stainless Steel .308 Win Magazine - 20 Round

I bought three of these. I wish I had bought only one. I put these in an Aero Precision M5 upper/lower combo with an Aero nickel boron BCG. The BCG rubbed significantly on the feed lips of the magazine. I filed the feed lips down and reduced the rub. The other issue is the right side of the mag would not feed. The filing helped, but then the follower went wonky and the rear of the bullet would not stay up for the BCG to catch it. I blew money on them, so I will continue to try getting them to work. Not going to even think of a return, as I was convinced the filing would work. (filed on all 3, of course.) I may get ambitious and cut my own followers or see if there is a fix for this. The other issue of the spring may be the real culprit. I bought 2 Promag Gen 3s and they fed like a bandit...I wanted metal, but will have to be satisfied with the plastic, I guess. At this point, I am with the person that said "don't want to re-engineer what they bought" paraphrased...

Super value, quality mags and fast shipping!

These magazines are awesome.. The compact look and detail is really nice.. Very excited about this purchase

Function is superb, looks great also!!! Good value!!!

I went into buying these reading that they “don’t work” for PSA PA10 AR10 Gen2…. They don’t. The feed lips are a few thousandths too narrow to allow the psa bolt to slide through. Also a couple thousands rounded off the top of the feed lips and bam they lock in great! Besides being questionable spec for some builds, the quality of the body is great. A great deal as long as you are willing and able to spend a few minutes with each one to make it fit right. I used a cold blue pen to touch them up after a few seconds or dremel’ing. Look great, function fine in my PA10 G2 now. You have to be handy. If not, stick to the Pmags.

I usually don't write reviews but I thought it necessary to make potential buyers aware. I built an Aero M5 and this magazine would lock into place but would not allow the bolt to travel forward. Had to use a file to open up the mag lips .05" in order for the BCG to travel freely. Front portion was also filed down to aid in loading/feeding. I bought this mag due to the longer cartridge OAL but not sure it was worth the hassle of making is usable.

Rounds 1-14 function fine, 15-20 will jam up. Significant burrs on the feed lips and front prongs (?) leave deep gouges in brass.

Battle proven is wht I choose metal mags.

The rounded springs are the problem. Order Wolff Squared Replacement AR-308 Springs. Simply Shorten the Wolff Spring a few coils so they fit the follower and base plate in the same direction like OEM. Presto runs perfectly.
While mag is dismantled insert it in the mag well while depressing the catch, release the catch and if it does not engage file raise the squared opening in the mag accordingly.

I buy and use these mags. Works great with no problems . I like this brand .
