Fitted to my .22 Kozak that was returning over 1.5 foot-pound variation in shot power on factory regulator.
Once fitted and left overnight at 250 bar to settle seals, the rifle is now giving only 0.2 foot-pound variation in shots - 11.7 to 11.9.
A bit of work on the hammer spring should see this tighten further.
Would highly recommend a Huma regulator as a replacement for the factory regulator - it transforms the rifle!

Fitted a Huma regulator to my. 22 Kozak that was giving the occasional hot shot, with the original reg, & it has improved the situation 100%. Rifle is now very consistent & no longer has a creep issue in between shots or after being left overnight. Would recommend a Huma regulator to any Kozak owner who has power consistency issues with the oem regulator. Rifle now happy at 11.47 ftlbs with 3.4 fps spread across 30 shots.

Easy to fit and stable before huma regulator was fitted first two shots were 57fps higher. Since huma regulator fitted I'm getting a 5fps variation from 250bar down to 90bar and gun now very accurate

Great product Easy to fit and stable before huma regulator fitted I was getting 57fps higher on first shot. Now I get only 6fps on entire charge from 250bar to 90bar and gun now very accurate

Excellent regulator, arrived set to the pressure I specified & was an straightforward fit, partly due to the .22 Kozak being easy to work on. Running the reg at 80bar & with a slight hammer spring adjustment it sits at 11.43 ftlbs & currently has a 6fps spread over a 30 shots. Only one small gripe, Huma breach sticker was not included in the package.

had trouble with reg creep on my kozak after reading up on this problem I decided to fit your aftermarket regulator to my gun I set it at 87bar for my .177 with minimal hammer spring pressure it sits at 11.4 ftlbs below our power limit of 12 ftlbs does not creep at all and is a great example of a quality product made by huma air I would recommend this to anyone having trouble with there regulator

Sencillo de instalar, compré modelo HP para .22 y tarado a 140 bars con jsb 1'64 gramos hace maravillas a 100 metros. Dar la enhorabuena al equipo de huma por su dedicación.

peter kay - 13-09-2019 09:33

huma products are top class second one i've fitted fit and forget no worries on high first shot all shots are the same great product
thank you

I highly reccomend buying this regulator. It solved all my problems, accuracy and consistency of shots is much better. My Zbroia Kozak .177 cal has reached next level and it exceeded my expectations. I would like to thank guys from Huma

What a superb piece of engineering, my Kozak 450.220 was fairly decent air rifle, but the shot string was rather erratic, after fitting the Huma regulator, it has become a fine and more accurate, no more irregular power spikes, varied feet per second readings and consistency has increased many fold. Only 2.3 fps standard deviation over 12 shots, that is a indication of how good they are.

My .22 Kozak has just had a 10 shot string fired from it and gave a 46.6 fps variation and a standard deviation of 15.29, so it will be getting this brilliant upgrade very soon.

Buy one, you will not be disappointed.

Great product, great service, will definitely use again

I purchased this regulator late 2018 for my Zbroia Kozak .177 cal around 7 Months back. The original regulator design is very good, but the Huma has proven to be even better in terms of fps constancy. I can leave the rifle for over a week between shooting and the POI is exactly where it should be when taking the first shot - none of this shooting 4 or 5 shots to stabilize the fps nonsense that plagues a lot of airguns out there!

Spread between shots with weighed JSB 10.34Gr pellets is between 3 and 5 fps, using resized H&N Sniper Mediums it is around 7 to 8 fps.

This regulator is awesome and is a very worthwhile addition to an already excellent and highly accurate air rifle.

Really good reg.2fps spread over twelve shots
