Having posted my 22 cal Disco on the classifieds I decided to run it through the chrony again. I remembered it clocking around 790fps last time I did. To my dissapointment it was shooting around 750fps, what the heck? I didn't change anything in a while! It actually bothered me enough to start thinking about making a power adjuster for it. The trip to Home Depot was very successful and after picking up up a couple of items I was able to put one together. 1st picture of it disassembled, 2nd pic is what the installed product looks like. . The white screw is a 8-32 x 1" nylon screw, cut to less than 1/2" it acts as a guide for the spring. The stainless steel screw is a 10-32 x 3/4" for adjestment. Even though it's an allen screw it can be turned by fingers.
 The results:
From 750fps to 876fps adjuster all the way in and 790fps all the way out at 1500-1600 psi fill. That's using 14.3 grain Crosman Premiers, that's almost 23 fpe. With 21 grain Kodiaks I got 733 fps for 25 fpe. NICE!!! I suspect much more air will be used but the Disco is not a weakling anymore!
 And yes, it was worth the 75 cents. It ay be not as polished and pretty as the $30 one, but works just as well
