I just done a breech seal and port mod and gained another 50 f.p.s. Opened barrel port to 11/64'' and counter bore 1/4'' and use the 1/4'' poly tube. Besides this the gun is still stock.Does a power ajuster increase velocity in this gun? Benson

I've been thinking about this mod for a while, nice to hear it worked for you. Did you bore the valve for the tubing as well?

I put in a home made power adjuster in my Disco.22 and I'm getting
low: 60+ shots @ 17 ft lbs 744fps w/ 14.3 gr CP's and
high: 21 shots @ 26 ft lbs 750fps w/21.1 gr Kodiak's (the CP's shoot around 880fps.)
I was hoping for a 200 fps difference between high and low, but the gun shoots so well now that I don't want to mess with the spring any more (stock hammer). It's great to go out plinking on low power and not have to pump for almost 70 shots!
I also put in a Big Ed HDD and it helps a lot.

Jeff I did not counterbore the valve for tubing. Looks like I need to install a power ajuster and an HDD. Thanks for the input. Benson.
