The AR-15 platform is fantastic, partly because of the ability to swap from one caliber to the next with very few parts changes. That also can make it a little bit dangerous. What if someone tries to shove a magazine of 5.56 ammo into your .300 BLK gun? The day could end in tears. Or worse. That’s where a new nifty idea from Faxon comes in: magazine bands . . .
It looks like these are basically the same kind of stretchy bands Lance Armstrong used to peddle. The idea is that you can temporarily dedicate specific magazines to specific calibers, and the bands will let you quickly and easily see if that dumb newbie you brought is trying to shove a square peg into a round hole — so to speak. Available from Faxon for only a few bucks, it seems like a pretty cool idea.
