What a great way to use two older Ruger mags. This is better than the longer BX mags, and works all the time. It also has enough weight to fall free from the action when hitting the mag release, no fumbling around trying to get it out of the mag well. Nice job TK, I will be buying other items in the near future..

I have a couple 10/22 and one American Rimfire that all use BX magazines. They NEVER have feeding issues with a rotary magazine like the BX-1 but occasionally would with the larger capacity box mags like the BX-25. Last year I purchased a Double Kross body to put my factory BX-1 internals into and fell in love. No feed issues ever and double the ammo when on the firing line. Later I purchased several more of the Double Kross bodies and now only use these in all my Rugers.

This item is both easy to assemble and helps organize and consolidate equipment. It also makes changing magazines slightly quicker.... The instructional video on assembly guides you step by step through the changeover and is easy to understand....

As a first time user, I found them easy to assemble and load. I purchased 8 of them. Loaded all and test fired. 100% reliable. They very easy to handle Swapping mags. Way easier than the stock clips.

Works very well in my T/CR22 (10/22 clone, but better). A couple of things that might be of some help. 1. Do not over tighten the bolt. 2. I use 2 complete turns on the spring . 3. Keep them clean. I went from 50/60 % (failures) to about 99 % with no failures. This works for me, you might have to change things for your firearm that works for you. Another item you really should get is the assembly tool from t/k, makes the job much easier. Taking only 5 mags (double-up) instead of 10 to the range makes for more fun. I load up 5 mags. at home the night before and i have 100 rounds ready to go. Would i buy again ? Well of course........

I purchased this to replace some magazines that were well worn. Upon disassembly to clean I noticed the inside of my original magazines were scored and I think this could have been causing some of my feeding issues. I purchased this to replace them. They function, as necessary. I tried them out on two firearms (I have two more to try them on) and had zero issues on a stock 10/22 rifle, but on my Charger Takedown (stock as well) with the plastic stock they were a very, very tight fit. I really had to align everything up perfectly to get them into the pistol. They work fine but were tedious to load into the gun. Just seems like the geometry is a little different from the factory mags on the top of these magazines. I still like the product but want to be fair to let people know of the issue I had. It won’t stop me from purchasing these again when I need to replace some magazine bodies. That is the only reason I can not give this product 5 stars.

this unit outside dimensions are perfect to the mag well! no slop what-so-ever. so nice to have the capacity and ease of use in one. only downside with it is with the use of the lula loader - the release lever hits the stacked mag body JUST enough to make ya struggle to get your double cross free but small price paid for an excellent product.....

This is a great product from a great company. Great customer service as well!

Excellent product. Easy to assemble and works like a charm . Thank you so much for this!
