    These are amazing mags. I was a little skeptical at first then I just said screw it, buy one. I ended up coming back and buying 3 more. The quality is great and they look really cool. I have had no issues with feeding or anything. I will buy again and again :)

    Very happy with the purchase. They are very light weight and work flawlessly. Lighter than magpul magazines. Very easy to swap springs to be legal in different states.

    Series 2 AR-15 Mag (15 Rd)

    Posted by Randi on 22nd Jan 2018

    I personally don't like the 15-rd limit laws when range shooting but I guess helps save a buck by getting tired of reloading mags.. with that being said, Hexmag has really produced a great magazine with this Series 2 AR-15 Mag! Very easy to take apart, constantly smooth spring, and honestly the easiest mag I have personally loaded! Highly recommend. My only complaint is that I wish they had the limit round capacity engraved on the shell for a quick reference when mags are checked.. but thats so minor, I stand with my 5-star rating!

    Hexmag 15 round clips

    Posted by Guy on 17th Jan 2018

    These magazines seem well made, have been working well in my AR. Colors help as I do reloads and keeping rounds separate is a real advantage. I would recommend these to anyone

    magazine is bulky

    Posted by Andrew on 18th Dec 2017

    I purchased these after hearing good things about them. I purchased several 15 rounds along with some 30 round magazines. I bought the 15 round ones to use in a 300 blackout with a 7.5" barrel so its a fairly low profile gun. I didn't want the length of the 30 round magazines for this gun. Well when they came in I found out that the 30 round and 15 round magazines are the same shell. The 15 round just has a plug in the bottom. If you are going for the "tactical look" with out the extra capacity these are great. However I like to use all of the space I have and if I don't need the extra space I don't want it in the way. I emailed the company through their contact section about a week ago to see if I could exchange or get a refund and have yet to hear back. But I did just receive an email to be sure to review the product, So I figured I would do so! The quality is as expected they appear to be great magazines. I just wish the magazine shell varied according to capacity.
