Hatsan 22cal wood flashpup qe regulator

I did my Flash QE with a Huma reg and the Plenum. Got it from Huma Air. Set at 110 bar from factory, gets a lot of shots (50 or better) Quieted the gun down and took alot of the "ping" out of it. I got into another project, but I believe it is well worth it and will tune the rifle some more when I have time this year. Mine is a .25 cal. The huma air web site has all the information you need to get the correct reg. Videos on U-toob will get you started and go slow if this will be the first time. I watched probably 5-6 times over before I said I got this. A chronograph will help if you want to jump way down the rabbit hole. Good luck! 
 
Thanks Guys

Do appreciate the input

Did more research on your suggestions which turns out one can learn a lot if you just ask

Blankshort 17 mentioned about dampening ping after installation

Yep, this one sounds like a ball peen hammer smacking a railroad track 

Seems most all sites have info on installation and adjustments but leave out the part #

Probably confirm part numbers before ordering

Another question, if a moderator will be more quieter then the QE original ?

Again 

Thanks Guys
