Curious. Mrod air says 500 fps for .22 caliber, but I've read posts that indicated this velocity can be adjusted upwards considerably. Has anyone done this on the earlier models?

Any suggestions, other than lighter pellets, to get the fps/fpe up a bit higher?

I just did a little back checking on my past posts regarding my .22 Airmax pistol.
I had chrony tests of it shooting in the 560 fps range. What I can't remember
is if that was after I slowed it down for more shot count. I originally thought
it was closer to 600 fps. I would have been shooting JSB 15.89. The gun was
accurate and a great shorter range pester. Trigger mod videos out there too.

Found this where one owner was getting up to 600 fps.

I've been working to power it DOWN and extend shot count.

Might have just been my luck, but out the box, it was faster that I really wanted. Once it broke in and settled down, without really doing anything but shooting, was NOT qute 600fps with 15.9gr. pellets (likely would have been over 600 fps with anything lighter)



Never shot a full shot count, but did "crank it up" and saw the same 15.9gr. pellets making 680fps (16.3 foot pounds) but never did a full shot count, so don't know for how many shots it could do that.

Still never touched the regulator adjustments, just fiddled the opposite way with the hammer spring tension and used the transfer port restriction screw.



Still well over 500fps.



Yeah...the "bugger green" grips did bother me... but they make good plastic-friendly paint.

Has any one bought the .177 ? Were are they made ? And are there any negative draw backs one should know ? Marvin

Lots of threads on these guns. Quick google search will
keep you busy for some time. Made in China. For the price
break they are impressive. Accurate and powerful. Pretty
easy to work on and if your read about them much many owners
bought both calibers after owning one.

Triggers aren't great. Okay and some polishing helps. Power
can be adjusted by regulator or hammer spring. The new model
has sights and a longer barrel.

Common complaints are some breech blow by. Can be adjusted
to seal tighter. Few air leakers. Over all I hear a lot
of happy owners with them.

I put the gun in backwards and it has room for the Red Dot sight.
