These are the diagrams I've been able to find.

Kozak (full size) 2nd generation (current as of June 2023, don't know when they made the change, but I believe it was late 2020).

Kozak (full size) 1st generation.

Kozak (full size) 1st generation (my poor, partial translation via Google).

Sapsan (unknown dates of production).

.22 S model 550 if memory serves . Both have creep up as you fire, doesn't really affect accuracy but it's annoying. I had one, did it sent it in to Top Gun to be fixed, a year later they broke it and sent me a new one, did the same thing, creeps up, you stop, to reload, it resents then repeats.

If I knew how to get at the reg and IF I had a tester for the reg, I'd look at it. It's not really a big deal, not actually effecting accuracy. I you look me up way back when, you'll see the mods I've done to make the HSA externally adjustable.

My speed is creeping up

It's a feature apparently, actually doesn't hurt anything but for the OCD among us it's an annoyance. I too contacted Huma a year ago as well as, I believe Lane but no joy.

I just checked my Hammer spring, found out that my lock screw on it was loosen. I tighten it up now my shot strings is look better.
It looks like the Kalibrgun Colibri aka the "Hummingbird".

Mine just climbs and resets, nothing loose. Just a flaky gun or operator, who know.

I drilled a hole in my stock to access the HSA, i drilled and tapped the HSA and put in a hex, have to be careful of that, it's thin but it works, I really fine thread, loctite, I'd have silver soldered it on but...don't have the right stuff any more, or machine up a whole new adjuster out of a set screw. I used a nylon tipped screw on the side to help it to move but not slip.

I'm pretty sure there is a thread with the pics.. but I tried to find my pictures and no success, IF I remember I'll pop off the stock and take some pics. if you aren't feeling lucky, I'd be careful. messing with the adjuster like I did. I'll take some pics when I get a chance.
