Hi Jasper,

I've heard that you can now buy the reg from Tench and fit it yourself if you want.

I'm not very good with rifles mate so I had it done by Tench plus quite a few other tweaks.

If your good with taking them apart then you should be ok I think.

The reg and the fitting it is £120 and I paid an extra £40 to £50 for the other tunes etc.

Well worth it in my opinion.

Si


spot on Si cheers for the info :thumbs:

Must admit I fancy like having a pop myself if he makes them for a Daystate Air Ranger! mind you £120 or perhaps a little more wouldn't be that bad. where is the guy based Si? just a rough idea of what county will do mate or if he has a Number you could PM it to me if its ok :thumbs:.

If I can get this gun running more consistant from a full charge to top up I will be made up, at the moment I have lost a bit of interest in the bloody thing.

hi davy ,just measured mine and it adds 40mm on the cylinder ,when a bought mine was told could fill 225 bar,not sure on shot count ,

i know there a lot more work in fitting the reg in the airarm than the bsa ,he did my bsa while i waited and i asked him about the reg for the airarms ,he says it
takes him a day+

Hi lads,

Thanks for the nice comments.

Hi Davy,

I have taken some photos for you buddy which should help answer your questions as I’m not very technical with rifles as you know I just shoot them buddy.

The regulator is 3.5 cm so will extend your cylinder by 3.5 cm, not your barrel mate.

Tench told me that the regulator can be pumped / charged to 250 bar easily.

This gives me 65 to 75 full power shots from a full charge in .177 and 90 ish from .22 I believe.

I chrono-ed my rifle a few days ago and it was doing an 11.83 ft/lbs average over a 10 shot string.

The MAXIMUN shot deviation was only 3 fps between shot 1 and 10 which was pretty amazing and just shows the regs quality.

The pellets were washed and lubed Bisley Magnums at 10.5 grain.

Normally a full charge of around 190-ish bar gives the Ultra 30 very good usable full power shots in .177 without a regulator using the sweet spot technique.

Si

hi buddy
thanks buddy,so it sits internaly then,just like the BT one i took out!
it was playing up so took it out and replaced the resivoir with a standard karbine one.
may think about having it done,but just have polished hammer & rail on the AAS410K.and next project is to polish trigger sears & replace crinkle washers!!

after polishing the hammer & rail i got my PB in the local HFT course of 52 :thumbs:
so i will say it goes to polish youe hammer & rail :thumbs:
