The velocity spread problem is fixed, still experimenting with hammer springs and port size from air cylinder to barrel a bit but am a lot happier with it now.

Think it is just…Read more

I tried a 40 mm hammer spring of 1.0 mm dia wire and even with the main valve spring…Read more

Posted questions on some UK forums but haven’t got anything useful off them, several suggestions of sending it to the UK importer but I have found them very vague or unhelpful when I have tried contacting them.

Not sure if I am on the right track but tried sealing the hammer area and under the trigger mechanism…Read more

I am still waiting for a selection of O rings to arrive to, hopefully cure the leak from the cylinder end, I got some 16 x 2 but they did not stop it entirely.

When I got the huma back from service the test document said it was set at 85 bar but I have tried turning it up since and think it is on 110 bar now, didn’t take note of what it was when I sent it.

I have been doing some more tissue tests with the stock removed and if I turn it upside down with the…Read more

I am in England and we have some pretty draconian laws about most things that can be considered weapons, like a 12 ft/lb muzzle energy limit on unlicensed air rifles, the…Read more

Miksatx – Yes, new Lane Mk9, it’s .22

gku – could you give a bit more info on how to use tissues to test the O rings?
I am wondering about changing O ring size on the air cylinder where it goes into the block to something a bit thicker as was…Read more

Fps goes up and down, am not averse to a bit of meddling but I haven’t clue what could be causing this, from changing the regulator I thought it seemed a fairly easy gun to work on.

There are no leaks from the main valve or the fill valve.

My first thought was regulator so got a Lane Mk9 but it has not made any difference so…Read more
