I know this has been discussed many times before. Been busy lately with life, work and family and not tinkering. Just finished a side lever for the .25 NOTOS . Was really liking the mods done by Genob and waiting on Firewalker to complete his side levers but decided to try it myself. Only using hand tools I think my first prototype came out ok but I will try several others to see if I can improve. I also want to make one for my .177 bottled PP750 and .22 NOTOS. All 3 have drop block and bottle mods with 16.9 inch Crosman Akela and KRATOS barrels and full shrouds with crosman baffles. Today I was shooting 20 grain .25 and averaged 780 fps with 3500 psi fill and reg set at 2150 psi out of 1 mag.
