Air Arms Combat, Love it !

Turn the spring guide down and sleeve it rather than remove it altogether, go for a larger spring as Jon said so it is snug in the plastic piston liner and ensure that you get the correct metric O ring for optimum performance, I also fit a slightly larger ratchet dampening oring to reduce the cocking rattle. Most of mine have very little preload when reassembled and I find this works best. The early SA Jackals were coming out of the factory running well over power at one point.

The cocking slot and cocking lever can usually use a radius and polish.

This is exactly the same action as went in the Khamsin and SE90 so it is perfectly capable of full power smooth performance, while the 'flash suppressor' is iconic, a silencer transforms the performance.

Pellet choice is important, they usually do well on superdomes - these also feed nicely.

Always wanted one.
Bought one a few years back.
shot it once.
I can still hear it twang now.
Hated it
Sold it.....
Wanted another.this time I got a belter from a friend who has around 50 of them.
This one was fitted with a ram so no twang and no ECHO echo (....echo)
Silenced, auto load,sa80 sling, metal mag,m16 grab rail rear sight......lovely.

That all helps a lot ! Did you buy a silencer adapter? or have to make a custom one? I would like to fit my silencers on it!
But the 'flash suppressor' does look soooo cool LOL !

On the tech side it "seemed" at one point to be doing 10fpe, but the odd shot (say 1 in 5) at 7fpe? piston washer is original and even though not had much firing at all I have ordered new ones from here : http://spares.bagnallandkirkwood.co....-piston-seals/

Thanks for the help !
