One of the things I love most about the AR platform is how versatile it is. There is almost an unlimited amount of different calibers you can build an AR in and its very popular for many AR owners to have multiple different caliber uppers for a single lower. As you can imagine, this also opens up the possibility of chambering the wrong ammunition into the wrong upper which can be extremely dangerous to the shooter and those near by.
In the past I’ve resorted to writing on the side of my magazines with a paint pen and have even had a special design dyed onto the side of a mag for me just so I can make sure I don’t make that mistake. The issue is this permanently marks these mags as that specific caliber which kind of sucks when you want to just grab some mags and go. The new Magazine Marker Bands from Faxon Firearms should help make this a whole lot easier.
Basically they are a thick rubber band which has the caliber information on it that fits tight around the bottom of the magazine. Currently they are offering these for three of the more popular AR calibers which are 5.56/.223 (Blue), 300BLK (Red) and 7.62×39 (Yellow).
Each caliber is available in a 10-pack for just $10 with FREE SHIPPING. Get yours now at www.FaxonFirearms.com.
