Volquartsen Custom is selling an interesting muzzle break. It is called the Forward Blow Stabilization Module and is designed for Ruger 10/22 rifles and Charger pistols, but will fit any rifle with .905 – .925″ diameter rimfire bull barrel.
Instead of porting the gas that exists the muzzle to the side or backwards toward it ports it forward at an angle.
From the product page:
Conventional wisdom tells us that compensators/muzzle brakes increase noise to the shooter. Our new forward blow stabilization module is designed to offer the best of both worlds – less recoil without the increase in noise.

.22 LR rifles do recoil contrary to popular belief and you notice this when shooting competitively. Saying all that, you can call me skeptical on how effective this would be. Still, I am willing to keep an open mind and look forward to some intrepid shooter taking photos of this in action with a high speed camera. The device retails for $109.75.
