WARNING You must be 18 or older to purchase shotgun or rifle ammunition and 21 or older to purchase handgun ammunition. Please reference our requirements for ammunition orders to "restricted" states HERE. Always make sure you use the correct ammunition for your firearms. Ammo cannot be shipped to a PO Box.
If you chamber a variety of different AR15 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 SENTRY knows just how important it is to safely, quickly and efficiently identify ammunition calibers, which is why they pioneered the first-ever colored rifle ammunition identification system - the HexID Color Identification System. Having the peace of mind that your investment, health and safety are all accounted for using the color-coded magazines that can be changed without tools, and in under 1 min, has changed the industry.
