If you’re like me, you can never remember how many rounds you have left in your magazines. I know that I should know, but I don’t. For those similarly afflicted, Radetec has started shipping a round counting grip system that will check your ammo levels every time you fire a shot and let you know how many trigger pulls are left until the gun runs dry. There are three versions: one with a single light that lets you know when there are three rounds left, a two digit display (above) that shows the total round count, and an AR-15 version for standard magazines. Prices are $160, $170 and $195 respectively. They’ve given us one to try so we’ll let you know how it works… as soon as I get some free time.
