    Well, I can definitely say that did restore the rifle to it's full operation plus some. It's whipping out the Stoeger X-Speeds at just under 590 fps. They are only 5.6 grains but that is still just a bit better then it was stock (+50 fps) and much better (+150 fps) after the attempted pump cup mod. I also noticed that I can increase the fps about another 50 points with 12 pumps as opposed to the normal 10. I'll keep it at ten though as right now it shoots just under legal with normal 7.3 grain HP. Valve plug is a cool mod!

    I think Eric still sells a ftp kit for the 7 series: a stock valve with no bleed hole, and a flat top piston.

    I've found the plugged bleed hole prone to cracking the aluminum around the repair over a fairly short period of time (this on a pump&dump build)

    The S&A kit makes good sense in this respect, and it isn't that much of a cash out lay.

    Regards,
