Bolt Racker Handle Compatible with Ruger Mark III, IV, IV Ruger Mark 3, 4 Lite Pistols -Harden-Aviation Aluminum

This is a solid product. Previously I had a tandemkross charger on my mkiii. Not saying it was a bad product by any means but the last couple times I took it to the range it kept coming loose. Upon closer observation I found it was cracked and the screw was slipping. I didn't want to spend $50 dollars on another one so I figured I'd try this Tusog model. This thing is not going to crack in a hundred years. Very heavy duty. Yes it doesn't just slide on. I jammed a short screwdriver in the slot to spread it apart enough to slip it right on. I'm liking it and it's half the cost of the tandemkross model

If you have difficulty installing with the pistol laying flat, try turning it vertically. It went on like butter. I tried reviewer recommendations to use a taped screwdriver and still scratched the ring, and it still didn’t go on. Then I tried holding it vertically (my method for locking the chamber on my other pistol) and voila. Too bad it’s scarred but it’s still half the price of the name brand.

Gives a way more positive engagement with the slide on the rugers. Way more comfortable to use also! Save your fingers for extended sessions. Can't recommend enough

I put this on a Ruger Mark 4 75th anniversary edition. It didn't just slide on so I took the bolt and passed it through the other side and put a penny in between both halves. This forces the bolt as you turn it to push into the penny and pry open the halo. You just keep turning the nut until it passes over the bolt and then you back it out, remove the penny, and pass the bolt through the correct side and tighten. It should be like this in my opinion because a flexed fit that also is bolted reduces the likelihood of it slipping off which would be a hazard. I shot about 200 rounds with it on and only had one instance of it failing to rack properly and two shells that didn't fire. I was using CCI standard velocity ammo. That failure rate is about the same as what I experienced without the halo so I don't think it's slightly greater weight has any impact. For me it works and is half the price of the compeitor.

Make sure it has slanted grooves on the bolt (MK III & IV) excellent grip. great fit and good value.

Fits very well and looks great. Watch the install video before trying to install so you don't mess up the finish. Give you a much better grip. Price is definitely reflected in the quality of the part.

With a bit finagling the racker ring went on my Ruger Mark 4. Feels great and is easy on my pull finger.

Great addition to the stock Ruger Mark IV bolt charging system, fit and finish is outstanding. Great price and great value.
