The HexID Color Identification System is based on the principle that color is the simplest way to mark your magazines. It is the ideal complement for three gun competitions, proper storage, law enforcement officers and anyone who uses more than one brand of ammunition or multiple caliber rifles.

If you chamber a variety of different AR-15 calibers, then you know marking your magazines is much like a home improvement project. (There's usually a lot of paint and tape involved.) But at SENTRY, we know just how important it is to safely, quickly and efficiently identify ammunition calibers, which is why SENTRY introduced the first-ever colored ammunition identification system - the HexID Color Identification System. Having the peace of mind that your investment, health and safety are all accounted for using our color-coded magazines that can be changed without tools, and in under 1 min, has changed the industry. We think you'll want to buy more magazines.
