i polished all that needed it,sear hammer etc..enlarged the barrel port.couldn't quite get it to .160 like the valve.got it at .156,cut the poly tubing.i did the transfer port angle,sanded w some wet\dry sandpaper.cleaned it all put back together.now i've realised,i kinda got ripped off.custom pfftt.just what you want on it.needs a new piercing pin.put the 2289 ported barrel on it.haven't ported my 24" yet.need to hone my skills.really need a cheap drillpress.i have shot it 6-7 times.still need to put the scope back on,also the front sight.makes more noise now.my dog just don't like it!people popping fireworks rite outside,me popping pellets inside.stressing him out.so i started to feel bad 4 him.and put it up.did shoot an empty airfreshener can @ 20 ft.went rite thru it.nice.pretty sure when the pressure gets low,all the rest will leak out.getting my mind set on a economy boss valve from crooked barn.
