This is a nifty little gadget of excellent quality and design. Far more compact and reliable than the big 25 round banana mags on the market, and only 5 rounds less. I was so impressed that I bought a second. Now, with one in my rifle and one in my pocket, I have instant access to 40 rounds of fire power.

I like being able to see about how many rounds are left in the magazine. The dual mag is easy to assemble from the Ruger 10/22 mags and it's nice to have 20 rounds at a time to plink with.

This was a trial purchase to see if we would recommend to our customers. They answer is: YES! Excellent products. Does just what it is supposed to do. Easy install. Will be buying several more in the near future.

Added to an order for convenience of a buddy, who already has several and loves them. He's notorious for being fussy and super-critical about things, so I'd have to say his repeat purchase would constitute a good recommendation.

I really like this magazine housing.. Nice to see the bullets and its less chunky than the triple couplers.. Will be buying another soon.. Installation was a bit of a pain without the right tool but I managed fine with some locking pliers

20 years ago I made a similar item by joining two Ruger magazines. This is a far superior solution. It is shorter than what I cobbled together, and it is Clear!

An excellent product especially for a Steel Challenge competitive shooter However considering that TANDEMKROSS is providing only a plastic body and the shooter is supplying the "guts" of the magazine for which he or she has already paid between $12.00 & $20.00. It is asking a lot to spend another $10.00 for the plastic shell.

This is one of the greatest products I have ever seen for any 10/22 fan. I build and shoot alot of 10/22's both for fun, and in competition. I have always found that stock mags are generally the most reliable, but wished there was a way to carry more ammo on the gun without resorting to a magazine coupler. I saw this product and had to try one. I am glad I did. I also bought the TK 10/22 mag tool, and it makes working with these (as well as stock mags) a piece of cake. I picked out two of my worst looking stock mags to harvest for parts, and in about 10 minutes (well, 8 minutes to clean the old in ternal components and 2 minutes to assemble them into their new home) I now have the best mag I've ever used for the 10/22. Function is absolutely flawless (just like a good stock mag), plus I now have the ability to carry twice as much ammo on the gun (without it being ugly or unwieldy), as well as being able to see my round count. I took one of these to my local monthly .22 sniper match, and everyone there had to check it out. I'm sure I sold quite a few via word of mouth, and I will continue to spread the word about this awesome product. I usually don't review products, but this one was just too cool not to. I will be ordering more very soon, enough to convert all of my stock mags over to this system. Thanks TK for making a great product at a good price.

This thing is a pain to put together, but not much more so than if you're cleaning a mag anyway. The assembly tool would likely help. I just used a small vice grip and watched the video. Have only fired a few rounds, but it seems like its going to be a winner. 5 stars on this one.
