Hexmag is one of many up and coming magazine manufacturers in the United States. They produce very nice AR magazines for the market, as well as follower conversion kits for caliber identification. They are easy to maintain, have a good aggressive texture for retention, and are built to withstand alot of abuse. None of their magazine body uses metal reinforcement, and they don’t need it due to how they designed the magazines.
This year at SHOT show 2017, Hexmag is releasing a few products that are going to, in my opinion, make them more competitive and put them on the radar for a huge number of consumers.
