I had previously ordered their Body only and have already commented on it. My curiosity about the polymer feed lips was piqued and I decided to order this assembled unit. I weighed both the unit I assembled and this unit on my digital scale and the unit I assembled using components from mags I had on hand and using their Green Springs weighed 14.7 oz compared to this fully assembled one that weighed 11.3 oz. The lips being the only Difference. I will edit/update this review after range time with both.

So glad TK started selling these as a complete unit, and they still work with my speed loader. look at feel great ! Another home run for TK

I thought this would be a good addition for shooting steal plate challenge in a league where I have to do a mag change. I practiced several times and used it twice in competition. I had one failure to advance a round, I chalked it up to being new and that was the only time. I do like the concept and it appears to be well made. Here is my biggest issue, I instinctively wanted to flip the mag forward to get to the other side - going either forward or backwards seems more natural to me. However, the mag comes out and you have to flip is sideways left or right. Notice in the video of the mag the guy pulls the mag out and holds it against his body to flip before reinsertion. It is just not natural. You can hold it in your hand while practicing and spin it between your fingers but that isn't practical in competition. Is there a way to make the two sections modular so they can come apart and the shooter can decide which way they want them aligned for their style of shooting? I can shoot a 15 or 25 round mag but am required to do a mag change, with this orientation, it isn't much if any quicker. It appears to be durable and well made so I anticipate it lasting as long as I do. Because it wasn't as fast as I think it could be, I gave it a 3. Also consider putting finger holes/grooves in the center where it pivots if you keep the left to right configuration. You could then grab with your hand and pivot between your thumb and middle finger.

Love it shoot flawlessly Might get more in future

I love these magazines! I load them before a match and I am all set with enough loaded ammo to shoot my practice rounds AND the match! I have two of these so I have 40 shots loaded and ready! Another GREAT product from TandenKross! Making my good gun great!! Thanks!!

I purchased this mag to shoot a 22 2gun match created at our local gun range. You always have to do a reload due to 10 round capacity so I bought this so I would not drop a mag on the ground during reloads, I just rotate it to the next ten, I have noticed some brand mags fit tighter than others, this one was on the tighter side which made it a little tougher than some to reinstall in the Ruger SR22 rifle I was using. I have not tried the mag in any other 10/22s to give a comparison. I plan to buy more.

The DoubleKross for Ruger 10/22 worked well in the Bergara BMR Steel. The concept is handy and never had an issue feeding. It's a bit difficult to load, but those mag's are always a little awkward.

after you slightly sand a high spot on one side of the magazine, they work great not hard to do and worth it!!

Looked interesting so I thought I would give it a try. Works good, looks good
