Theoben Theoben Eliminator

I got this one a few ago and it’s been sitting on the safe until this morning. A quick run over the chrony showed it’s running a ten shot average of 823 fps with 15.89 JSB .22 pellets. I’m not sure which MK it is, anyone have input on that? I don’t have a pump for it, if I track one down, how would I change the gas pressure?

Under the screw at the rear of the compression tube is a Schrader valve. The pump hose fitting goes into that, DON'T over pressurize and use a chrony for confirmed fps NOT BAR/PSI, it is much more accurate. Over doing it can burn seals, damage the gun, optics and make the gun very unpleasant to shoot. You right at 24fpe now and many find this or even lower to be a very nice spot to be. The Elis' in .22 are rated by "factory specs" to be right at 28fpe pending pellet...

I think Evolution trigger is Mk3 and uses 2 O rings for the piston seal.
