Simple 9mm mag
This item is very easy to install and use. Slides right in to a magpul magazine. I did have to slightly modify one due to it turned my gun into a uncontrolled automatic. The other ones worked flawlessly.

Great quality
This is by far the cheapest and easiest option that functions correctly. It allows the use of a non dedicated lower while still functioning with some very minimum break it. I trust this product with my life for my 9mm PDW upper.

After break in I ran 100 rounds not a problem.

Perfect for my use
I had purchased this product to try the new 9mm upper, blowback action. I had used some snap caps at the beginning to check the feeding of the magazine conversion, worked flawlessly. Loaded the magazine with 30 rounds, only fired 40 through worked flawlessly I'm happy with the purchase, I would buy again. I only bought this since I didn't have the glock mag lower receiver yet, Note: If anyone is using this on a glock magazine upper receiver, that has a LRHO on the upper receiver you will need to remove it, once the 3 screws were removed feeding was not interrupted by the lever on the inside of the upper receiver New Frontier Armory upper receiver was used.
USWorks great
I was skeptical at first. After 1200 rounds , bolt hold open still works and zero issues with ejection or feeding several brands of ammo. Installation took less then a minute. I have 2 of these in some Gen 2- 30 round Pmags. They are adjustable to fit all the way down to a 10rd Pmag.
