"Game Changer" .22lr Compensator from TandemKross

  Compensator's for small caliber handguns can seem pointless to some. After all, .22lr doesn't have much recoil. But, I tend to believe that all calibers benefit from reduced recoil and muzzle rise. I tend to think TandemKross feels the same way I do. After all, they did send me the Game Changer comp to review.

  I installed the Game Changer on my Ruger 22/45 MKII. The barrel had been previously threaded to the 1/2-28 that the compensator is designed for. So I installed the supplied O-ring that they use as a type of crush washer and seal. Then screwed the Game Changer on and aligned the top holes up.  There is some resistance once the O-ring starts getting pressure on it, but it isn't a lot. This compensator does not have bottom holes/vents. I prefer this to other styles that have vent holes all the way around the compensator. 

  So it is time to tell my experience with the Game Changer. I originally thought the name was a little boisterous, but then I shot it. This little compensator does a great job of reducing the recoil. Since it didn't have much to start with, it took it down to almost nothing! But that's not all, it also reduced the muzzle rise. On a side note. While at a steel challenge match, I was talking with a guy who had been using the Game Changer for a couple of years in rimfire open class. He told me it was his favorite comp. So I am not the only one that likes it. Also when shooting the comp, you can actually see the gases coming out the sides and top. I did not notice it being any louder than without it, but it is only a .22, so it is not like a large caliber with a compensator.

  The Game Changer is constructed out of anodized aluminum. It has 4 holes in the top and 4 slots on each side. TandemKross says it has large ports for easy cleaning, and yes, you can get in there to clean out the lead and powder junk. As usual, it has 1/2-28 threads, the standard for rimfires. But there is one thing I don't like about the comp. It has a 1" diameter, so it is larger than the 22/45's barrel, and would also be larger than a 10/22 bull barrel. It is just cosmetic, but it would be nice if it was the same diameter to give firearm a smooth look. At 1.75" long, it is not really long either. It will also fit just about any .22lr that has 1/2-28 threads.

  After shooting the Game Changer a bunch. I've concluded that it lives up to the name. So if you are looking for an "actual" compensator, not just a diffuser, go look at TandemKross. They pretty much are a one stop shop for anything .22lr, not just products for Ruger's.

What others are saying?:

Keith @tandemkross.com: 3/5 stars

It's O.K.

Does help with speed of follow up shots. However leading causes accuracy to drop off rapidly.

Jason @E. Arthur Brown: 5/5 stars

Works great on my 22/45

Threaded on great, came down to the right amount of force to snug it on and sits flush with the ports lined up exactly straight up on the top. Definitely can hear the shots, almost louder than before. It seems to tame the already small recoil down even more.
