Ok - not great

I ordered two of these mags and I like the feel and look of them. One of them seems to be out of dimension though as it takes some force to insert and remove from the mag well.

Strong, light weight, reliable. Bolt holds open after last round. No issues with fitment in Aero, DPMS or Poverty Pony lower receivers. I wanted to purchase many more but only seven were in stock.

No problems

I purchased 4 of these on 5/22/2018 , I use these all the time for practice and the CMP matches that I go to . I have never had problem with these . The only problem is ,they are out of stock ,was going to buy 4 more to have on hand . Hope they get them back . Will buy more.

They feed and lock the bolt back fine but they’re hard to load and can’t insert when the BCG is forward.

Works Just Fine


Works just fine. I have a Smith and Wesson M&P Sport II and these work just fine in it.
