found the issue, pic below

the inner sleeve of the piston is dented, each time i cock the gun, the main spring has to go over that dent, creating that ratchet feeling and noise, will straighten that and reassemble

thanks for providing the link to the article Ace, seems a common problem with that power plant,

and yes, you were right marshman

thx for the input fellas

Yep, same thing happened to my Airhawk. BTW, one of the popular tunes done to these is to fit a tophat and reverse the piston liner: like so:

well Duke, after putting that much work in this rifle over the last few months, everything is finally right(i hope), think i'll leave as is for now

but, theory is confirmed, put the gun back together, ratchet sound and feel is now completely gone, again, thx guys

The 'pipe casing' or that sleeve around the spring, is more issue than it's worth. Some manufacturers (and some aftermarket kits) install these sleeves with the idea of reducing noise. Frankly, I've forcibly removed quite a few of these sleeves as a result of them getting a dent or a spring catching on its ridge (breaking the spring in the process). The Benjamin Superstreak had such a sleeve, and it caused the destruction of more than a few springs as a result. Yank it out, you'll be glad you did.

well Eric

without me asking, you answered 1 or 2 questions I had about that, ty;

1-what is the purpose of that sleeve
2-can I take it out without affecting the rifle

if it proves to be an issue in the future, I will certainly do as you suggest, wonder if replacing it with a homemade plastic sleeve (say from an ice cream container), would make the action more silent :|

in case someone wonders how I straighten it, I used the rounded end of a ratchet extension, with that, I rolled it back into shape :D

People have made sleeves out of plastics of different sorts, and this is what some of the aftermarket "tuning" kits do. While I'm not a fan of spring sleeves generally, at least if it's made of a thin plastic, the chances of it destroying the spring if an edge catches is alot lower than would be the case with a steel sleeve.

I've been using plastic pop bottle sleeves for ten years, since reading about it on a euro forum. I've never had one fail [or dent], they can help you to attain that "thunk" sound, if nothing else.

i will keep that as an option if ever take it apart again, truth be told, i find this one a pain to disassemble, so i wont if i don't have to, probably due to the strong spring, and a spring compressor not really made for that purpose(need to build one) :)
