Now, I have added a hammer buffer, and dropped my fps a little, and I get about 50 shots at 855 fps with the H&N 19.09gr. BCHE pellets, and the reg set at 120 bar.

It is just rc car fuel tubing that is placed in between the hammer and brass fitting that the cylinder screws into. This particular one I posted the link to is slightly larger in diameter than some. It is 1/10-1/8 scale nitro rc car fuel line. The one I used is a piece that is about 2.25" long. It doesn't wrap all the way around the trigger tube, so there is a gap between the ends to allow for the hammer stop screw. It is silicon, and stays in place, since it really has nowhere to go, and the hammer firing will make sure it is always in the right spot. If you use some that may be slightly smaller in diameter you may need a piece that is about 2.5" long. It really made a difference in my gun. If the gun is dry fired, the hammer barely hits the stop screw if at all. Does that make sense? I'm told it is similar to a bstaley mod? I think it is better, since it has more give, but is thicker and allows more movement at first. I gotta hit the sack, but I can make a diagram tomorrow if you need me to. It literally wraps around the wall of the trigger tube, and sits between the hammer and brass fitting that the cylinder screws into though. I hope I making sense?
Thanks shark .Oh and 50 shots at 850 would make me very happy lol !!!

It would be kinda hard to do the BSB with that screw stop. This looks lie a good alternative.
If you try it, I would love to hear how/if it worked in your case! As far as I know, I haven't heard of anyone else doing this specifically or their results if they have. I would just like to have my results duplicated on another gun etc.

As far as I know, I haven't heard of anyone else doing this specifically or their results if they have. I would just like to have my results duplicated on another gun etc.Just ordered some this afternoon. In addition to my .177 I just picked up a .25 will try it in both.What did you set your reg at for the .22 to get 35FPE? This one came with a reg in it, just need to fill the valve holes and tune it. In fact I got 2 cylinders with the gun, a long and a short. Thinking of leaving the reg in the long cylinder and removing the reg from the short and use it for high power. Would be nice to use min preload with the reg'd cylinder to get max shot count at like 35-40fpe and then be able to just crank up the spring, switch the cylinder and get 60-70FPE for a mag.
Awesome, I can't wait to see if you get good results with it! My .22 can do 35fpe with the reg where it is(120bar) if I give the spring a turn or two.
I took a chainsaw file and did the stock mod , drilled the 1/8 in hole behind mounting bolt also. Makes it way easier to adjust for sure. Going to look for screws tonite and do the valve mod .What size do I want ?6/32 , 4/40 , or 11/64 ? I keep seeing different sizes in differant posts
I plugged 4 of the 6 holes . didn't have one line up, and drilled valve seat out am now waiting for jb weld to dry . tracking also says my regulator is in N.Y. as of last nite Only thing I don't look forward to is pumping the cylinder up from zero again . And then again when my regulator comes in .... Lol.
I didn't open mine up as much as you did , I'll see what I get and maybe open them more ?Thanks for helping me with this
