20 rounds, one mag body, two 10-round compartments; it's the fully Assembled TandemKross DoubleKross Magazine For Ruger 10/22! Featuring a clear body, the DoubleKross gives you the ability to count your rounds! When your first ten rounds run out, just eject, flip, and go again! Rather than one single 10-round magazine, or one 20-round magazine, the DoubleKross gets you the convenience of a 20-round mag in a smaller, lighter package! Plinking for fun target practice, in the heat of competition, backpacking, or anything else; the DoubleKross is the pinnacle of convenience and functionality. With a DoubleKross Magazine for each hand, you now have the equivalent capacity of four factory magazines! These magazines are carefully assembled and tuned to the optimal settings and are fully ready to go the moment you take them out of the packaging. As durable as they are lightweight, these upgraded magazines are great to have and will last a very long time! Get the Assembled DoubleKross Magazi...
