    Unexpectedly Great Product

    Posted by Tyler on 29th Jun 2021

    I ordered these during a sale because they were cheap. I did not think I was going to get a quality product due to price alone, but I was mistaken. The spring is quite stiff, but not so much that it is a pain to load all 20 rounds. The polymer these are made of feels of similar quality to another well-known competitor. The construction feels solid. I wouldn't feel badly about accidentally stepping on one as these are engineered quite well. The hex grips feel nice in hand and offer superior retention. The hard edges on the pattern allows for good control even when your hands are slippery. All in all, these are a great product made by a great company who stands behind their product. I just bought 5 more and can't wait to get them.

    AR 10 Hex Mags

    Posted by Justin Dennis on 19th Sep 2020

    These mags work great in my most recent Aero Precision AR 10 build... Magpul 25 round mags were sloppy in the magwell & continually failed to feed properly in my build... Your mags performed perfectly!

    Runs fine. I would like to see it with a 25 round capacity.
