I just returned from the range with my Remington 700 Sendero in .300 Win Mag, with your JP Recoil Eliminator (JPRE-424S) installed. It's phenomenal! It has totally tamed my .300 Win Mag; shooting 180 grain bullets was smooth and easy! Please thank your design engineers for me! I'm a fan of high performance in engineering whenever, and where-ever, I find it. I'm be a fan of your company from now on; keep up the great work!
