  1. Mags need to be tweaked 4 Star Review

    Posted by on 28th Apr 2017

    The mag insert (cartridge follower) and spring seem to be pretty stout. I had to load up the mags to capacity and let stand overnight so the springs would let off a bit. Then the slide on my AR was more willing to close fully when going into battery.

  2. Fast shipper 5 Star Review

    Often orders from gun websites take forever to ship. Not these guys. This mag works great in my AR15 9mm conversion. Although I had to file one lip about 1/32 of an inch.

  3. Great Magazine 5 Star Review

    Posted by on 1st Jun 2016

    I have put several hundred rounds through this magazine now. Initially it was stiff to load, but after a couple of full magazines it became easier. It has not failed feed or slide in and out of the lower easily.

  8. Worked great in my 9mm CMMG 5 Star Review

    Posted by on 15th Mar 2015

    Magazine was new and extremely dificult to load only negative I see seems follower could slide smoother . I will definitely buy again, I plan to D/A magazine and smooth out or lube internals. Very happy I fund this 9mm ar site.

  9. Excellent value 5 Star Review

    Posted by on 8th Mar 2015

    I purchased one each of the 20 rd, and 10 rd ASC magazines wanting to try them first to make sure they would function correctly in my PSA build rifle before ordering more. They work flawlessly, and are "drop free" in my build. I plan on ordering a few more as money permits. I was hoping ASC would make a 32 rounder in the same configuration, but will use the 20 for now as I haven't found any other mags that work as well as these do. Other mags I have tried I had to do minor filing and fitting to get them to lock up, but these snapped in and worked great right out of box., and are very good quality material and construction. Thank you..
