Air Arms S200/CZ 200 Regulators

I supply the popular DIY fit HuMa regulators for your AA S200/CZ 200 to flatten the power curve and increase the shot count. Hunting for the sweet spot and counting shots will become a thing of the past. 

Please note that if you have the S200/CZ 200 with a pressure gauge as standard then it is not possible to fit a regulator unless the gauge is replaced with a quick fill (found on the current UK models or one of the HuMa quickfills found in the eShop) or with one of the pressure gauge & quick fill adaptors that are available from the eShop.

 There are 2 types of HuMa regulator available for the S200 - an internal regulator and an external regulator. Neither regulator involves drilling a hole in your air cylinder (the regulator is still vented for reliability), unlike some of the other regulators available for the S200. The internal regulator fits inside the air cylinder, therefore the rifle looks standard when the regulator has been fitted. The external regulator fits between the brass firing valve body and the air cylinder, which adds 45mm to the length of your air cylinder.  

Tools are available from the eShop to help with clamping and removing the ends of the air cylinder, which can be really tight.

The Tench/Tweaky (discontinued) regulator can be serviced and I sell a seal kits for them in the eShop.

Typical shot count for a HuMa regulated S200 is around 70+ good shots at around 11.5ftlbs in .177 using JSB Exact Heavy and 80+ good shots at around 11.5ftlbs in .22 using JSB Exact but it does vary from rifle to rifle. 

 Air Arms S200 Pressure Gauge & Quick Fill

I supply a pressure gauge & quickfill for the S200/CZ 200. They replace your current quick fill or pressure gauge. It is a great upgrade for those of you who want to have quick fill rather than removing the cylinder to fill it each time or for those of you who have the T bar quick fill but no gauge. Tools are available from the eShop to help you clamp and remove the ends of the air cylinder. 

 Air Arms S200 Barrel Threading

I can thread your barrel to 1/2" UNF (probably the most common thread used for silencers/moderators) so that you can get rid of the silencer adaptor and fit the silencer/moderator of your choice, directly to the barrel. I do not need your action to do this work, only the barrel, which is very simple to remove.
