I had purchased a Sumatra .22 quite some time ago and thought it too nice to take out, I'm over that now LOL. When testing it to try for FT velocity would climb higher and higher. Come to find out the velocity adjuster detent spring was just too weak. I was not comfortable tackling this, as I had no idea where to start. Len to my rescue again. He made it look like it was easy but I know I would never have been able to fix it myself. Thanks Len you made one happy gimp it is a joy to shoot. I can't wait to get it set for 20 ft/lbs and do some target testing.
