I just bought 2 more for my AR-45 because how impressed I am about the quality (they are metal and made very well) and the price.
If your weapon accepts these mags, don't hesitate to buy at lease a few. You won't be disappointed.
No mod mag for MPA10T pistol
Review by Brett
Verified Buyer
Ordered the grease gun mags on a thursday, received them the following Monday and only selected the cheapest shipping at $10 for the 3 mags. Outstanding order processing and shipping. Usually I have to wait for other companies to process your order for at least a week or 2 and these guys get my order processed and shipped to me in 5 days which included the weekend. Just awsome. As for the magazines themselves the over all continue looks great (after cleaning the grease off) they all fit my Master Piece Arms MPA10T just as good as my factory mag and even though I did NO altering to the mags I couldn't pull them out of the mag well even forcefully. I only put 10 rounds thru each mag (ammo costs prevented me from doing a full 30 Rd per mag function test) with only 1 false to feed which was my fault for not fully seating the mag. My gun ran like a champ with them so now I'll be on to loading a mag up fully and letting it sit for a month or so and see how it feeds then. Other than that for the $15.95 these mags are you can't go wrong if you are gonna run them in a MPA10 varient in my opinion. Can't wait to see if they get any sten mags back in to try out in my MPA30sst. Figures crossed :)

I had a military mag that wouldn't work in my Vulcan V10-45. This mag worked great!
These work flawlessly!

These work flawlessly in the MAC 10 during both semi auto and select fire. I've never had a problem with them during loading or 'unloading' at any rate of fire. I would not hesitate to buy more of these. I prefer them to the originals and I recommend them to friends with MAC 10s.
Better than MPA10sst original factory mag.

I was looking for a cheaper mag for my MPA Mac 10 45 and I happened to run across these on sale for $15.95. I was really impressed with the quality of these mags. They are well built and have a nice blued finish. They look and seem better built than the orginal mag that came with my gun. The Masterpiece Arms web site wanted $35,95 plus shipping for their mags. These are cheaper and better quality.

I bought ten of these magazines and each one functioned flawlessly with the Lage thumb release grip for my M10/45. Great fit and finish on the magazines, so much nicer than the surplus originals.
