TandemKross Halo Charging handle

  If you have been around certain types of handguns, like the Ruger MK series, you know how hard they can be to cycle by hand. This brings us to the "Halo" charging ring by Tandemkross. The Halo is a nifty device that clamps on your existing charging handle/slide. Tandemkross sent me the Halo for review. It is one of the few made for the square style bolt on the earlier Ruger 22/45 and MKII's.

  When you first get the Halo, you notice that it is a real simple design. It is basically a squared off ring with a slot and a bolt. Simple yes, but more importantly is the function. Once I mounted it up, I immediately found it easier to cycle the bolt. All you have to do is put a finger inside the loop, and pull back, then let go, and your done. I had my whole family try it, and they all said it was way easier and more intuitive. I was also told it made the 22/45 look like a space gun.

  Of course I was also worried about adding weight to the bolt. After trying everything from sub-sonic to hyper-sonic .22lr shells, I put that thought to rest as everything functioned great! Now on the other hand, I was a little disappointed the the inside of the Halo ring was squared off. It digs into your joint a little when using it. If Tandemkross were to round the inside, it would be much more ergonomic. I wasn't the only person who thought this either. With the Halo installed, you can cycle the bolt the same way as before, if you want, but with the added benefit of the tabs sticking out farther than standard.

  Everything needed for the installation is included. Basically the screw and allen wrench. To install the Halo. Just slide it down over the cocking serrations/nubs. Install the screw, and tighten it down. I put some blue threadlocker on the screw, just in case. One thing to note, you can put the Halo on upside down. Yes, I did this, and it does still function fine. But put the writing so you can read it, and that is the correct way to install it.

  The Ruger series of pistols is not the only ones that Tandemkross makes the Halo for. Some of the others look a little different, but function the same. So if you are having a problem racking the slide, or know someone that is, you might want to look into the Halo series of charging handles.

Ruger 22/45 Lite Halo

This has to be one of the best upgrades for the Ruger 22/45. I got this for my wife because she has a hard time pulling back the bolt with her small hands. The halo ring makes it simple and easy for her to rack the bolt with just one finger. I also like how secure it is on the bolt, just a dab of blue loctite on the screw and its not going anywhere. Lastly, I believe the extra weight of the halo on the bolt helps cycle the gun better which is an added bonus. I would definitely recommend this upgrade for people who have trouble pulling back the bolt on their Ruger pistol easily.
