nicely built and good stock,however the seam inside the 3/4" pipe make's
slower open time specially with that pilot valve.

what i suggest is ,put 3/4 coupling then put 3/4" BRASS nipple and drag the barrel to the start of the brass nipple and done.

you have smooth bore that you can make a good round piston that fits with no gaps.
it will be more efficient
