The TandemKross DoubleKross gives you two of the most reliable 22LR mags in a package the size of the Ruger BX-15! Plus it’s clear so you can quickly check ammo count. TandemKross offers a great service kit to convert two 10/22 BX-1 mags into a DoubleKross 20rd mag, and you can use it for any field service or cleaning. Just note, this is just the DoubleKross body; you will need to use the internal parts from two Ruger 10/22 BX-1 mags to make a complete functional DoubleKross magazine. There’s an excellent video on the TandemKross website. I very highly recommend these mags if you have a lot of...

The TandemKross DoubleKross gives you two of the most reliable 22LR mags out there in a package smaller than the Ruger BX-15 15rd magazine! Plus it’s clear so you have an easy round count available anytime. If you find yourself stuck with a bunch of the 10rd BX-1 mags and you’re wanting a less expensive option for a high capacity mag, this is it! And TandemKross has a great kit available that makes it easier to assemble and service the DoubleKross magazines! Their website has a great video on how to assemble the magazine. They also have custom parts available for the rotary magazines and they have a great customer support team to help you out!
Pros:
Great Customer Support
Superb fit and finish
excellent fit into the magwell
Cons:
None

Any Ruger 10/22 use

I will admit the pricing does hurt a little for what you get where you have to take a part your old one and use parts to install into this. BUT I will say its totally worth it. The Ruger mag is highly used and the rotary body is one of the most reliable system out there. The downfall is its small. The 15 round option is a huge mag which is hard if you do competition shooting. That all comes down to this. It holds 20 rounds total. 10 in each side which is the max round count allowed in matches. Makes it easy to grab and switch for the next round. It is flawless and I am telling you. BUY BUY
Pros:
reliable
Small
Easy
Cons:
uses component from old unit
Best Used for:
hunting, plinking, competition
