I just picked up a new sendero 300win. And put a trijicon 5x20x50 green mill dot on top. The but pad dose not feel comfortable. All my other guns I have switched out the pad to the sims vibration. Ones and love them. I not sure if they make one for that gun or is it a grind to fit one? And the Mercury recoil reducer thing .??? Dose it work? Or hype. Can I put it in the gun or is that a job for a gun Smith? And I have no intentions of putting a break on the front.!! Thanks .
