TANDEMKROSS | GAME CHANGER | .22 LR
Keep the Dot Closer to the Next Shot.
The TANDEMKROSS Game Changer Compensator is a lightweight, purpose-built muzzle device for threaded .22 LR pistols and rifles. Its top and side ports redirect gas to help manage muzzle movement, making it easier to watch your sights and settle back on target. This is the Silver aluminum version, TK00N0005SSL1.
A .22 LR does not produce much recoil, but anyone working through a string of steel targets or keeping a red dot steady during practice knows that small movements still matter. The Game Changer puts that muzzle gas to work without the bulk of a heavy steel device. The Silver finish is a natural match for stainless barrels and silver-accented builds on a Mark IV, 22/45, 10/22 or Charger. You get that finished look without adding much muzzle weight.
Choose Your Finish
The original Game Changer comes in Black, Red and Silver. Choose the finish that suits your build; the function and standard 1/2-28 thread pattern remain the same across the family.
Designed Around the .22 LR, Not Just the Thread Pitch
The Game Changer uses directional top and side ports rather than a field of small holes. That layout is intended to counter muzzle rise while leaving openings large enough to make carbon cleaning less frustrating. Its aluminum construction keeps weight down, so it works especially well for a rimfire pistol where you want control without substantially changing the balance.
At the range, it is equally at home on a threaded Ruger 10/22 or a Mark IV / 22/45. The benefit is about how the muzzle behaves between shots; a compensator is not a substitute for a good barrel, a consistent trigger or solid fundamentals.
For a Threaded Rimfire Pistol or Rifle
If you are building a Ruger Mark IV or 22/45 around quick sight recovery, the Game Changer makes sense alongside a charging ring, a magazine setup you like and a trigger you can run consistently. On a Ruger 10/22 or Charger, it gives a threaded-barrel build a compact muzzle device without requiring a heavy steel brake. Explore our Ruger Mark IV upgrades, 10/22 parts or Charger parts for the rest of the build.

Frequently Asked Questions
How is the original Game Changer different from the Game Changer PRO?
The original is a lightweight aluminum .22 LR compensator weighing about 1.23 oz. The stainless-steel Game Changer PRO weighs approximately 2.83 oz and has angled gas ports. The PRO may be a better match if you want more weight at the muzzle.
Will it fit a Ruger Mark IV or 22/45?
Yes, if the pistol has compatible 1/2-28 muzzle threads and sufficient clearance. Not every Mark IV configuration has a threaded muzzle, so check the specific upper or barrel before choosing a compensator.
Does it fit a Ruger 10/22 or Charger?
Yes, on a compatible .22 LR barrel with standard 1/2-28 threads. For other threaded barrel options, visit our Ruger 10/22 upgrade guide or Charger parts page.
Can I use this Game Changer on .22 WMR, .17 HMR or other calibers?
No. TANDEMKROSS designates the original Game Changer for .22 LR only. For a different cartridge, check the caliber approvals for the appropriate Game Changer PRO rather than assuming the identical thread pitch makes a device compatible.
Does this come in Black or Red?
The standard Game Changer family is offered in Black, Red and Silver. This page is for Silver. For a different finish, view the Black Game Changer or Red Game Changer. All three original Game Changer versions use the same aluminum design and standard muzzle thread.
Will a compensator make my rifle or pistol more accurate?
It is intended to reduce muzzle movement and help the sights settle between shots. It does not guarantee smaller groups or replace the effect of ammunition, a sound barrel, a reliable trigger and consistent shooting technique.
What does the Game Changer include for installation?
TANDEMKROSS includes a flat washer and an O-ring. The combination used depends on the muzzle shoulder and barrel profile; follow the manufacturer’s instructions for your specific setup.
Will I need a thread adapter?
Only if your firearm does not already provide compatible 1/2-28 muzzle threads. Some pistols, including certain adapter-equipped .22 LR models, require model-specific hardware.
How do I keep the ports clean?
Like other rimfire muzzle devices, the Game Changer collects carbon and lead residue. Its comparatively large openings make the ports accessible for periodic maintenance according to the manufacturer’s instructions.
What should I pair it with on a Mark IV or 10/22?
On the Mark IV, the Halo charging ring and Volquartsen accurizing kit address handling and trigger feel. For a 10/22 build, consider our Viton bolt buffer and compatible trigger upgrades. These are optional enhancements, not required for the compensator to work.
