Scooter

I have a JP tank brake on my 260 and I installed this on my son's 300winmag. I believe JP says that it almost as effective as the tank.

"Working in other professional shooters, we arrived at last at a truly high-performance, match-legal rifle compensator that maximizes the potential of the common size limitation while maintaining nearly the same recoil reduction and neutrality that characterized the original JP Recoil Eliminator. To this day, the JP Compensator is the standout most efficient device of its type. Since its release, the JPTRE series has grown well beyond its competition origins. For years, it's been the choice of shooters who prefer a slimmer, more compact configuration without crossing over into a more tactical aesthetic."
