Absolutely. The lighter the projectile, the faster it leaves the barrel, which results in faster pressure drops, which in turn results in the valve closing faster, which results in less air escaping, which results in more air remaining in the tank for future shots, which results in more shots...

Looking for a 1911-style grip for the GK1 to experiment with. Printed OK - prefer a budget solution as this is to run a test. Thanks!

I believe that he has to change the power setting higher to get the same FPS with a heavier projectile.

OK, question for those participating in this "All Things Huben GK1" thread. When did Gk1 come with the traditional square print carbon fiber tubes, and when did they come with shadow carbon fiber tubes? I thought the later ones got switched to the Shadow but I see current ones back to the...

Yes. Designed this way - so that you have flexibility in placement.

Thanks. Just saw a video today form a link on the front page of this forum. The guy was shooing at 970fps and getting MOA at 50 yards. (0.58" group.) This is impressive for something so light and fast. A lot of lighter lead pellets do not do this well.

Thank you! Fantastic reply and insight on the GK1.

Thank you. You are gener Thank for being so generous with your knowledge and time. Deeply grateful.

I'm coming late to this thread but this is pretty 'insane' for a pistol - 17 rounds from 310 bar, 44 ft-lbs avg. WhatI'd like to know is how does the .22 work for same pellet weight? What kind of ft lbs would it do for 17 shots? Or would one use the 20 grain instead for 880fps and 17 shots?

Thanks for your very helpful comments. I've not considered the rigidity (or lack thereof) of the shroud. I was actually thinking of experimenting with a 21-oz scope that goes up to 12x. I've got to think about this. What I've heard of the GK1 is about 65 yards for hunting smallish birds, so it...

May we have details such as physical length/diameter? And 'mouse fart' even at the full 80+ ft/lbs power? How many sections and length on that? Thanks.

Curious if you experimented to have a sense of how fast you could push the GTOS and still get excellent accuracy? Thanks in advance for any insight.

Been a while. What did you find out after you experimented? Curious how fast have you shot the GTOs and still seen excellent accuracy? Thanks for any insight.

Resurrecting a very old thread. Now that you have had years to accumulate more experience, any additional thoughts on the GTOs? And how fast have you pushed them and see them remain stable/accurate? I'd love to go 990fps and 50 yards at MOA if possible.... Thanks for any insight.

SUPER helpful. I'm surprised how well the .22 hold up against the .25 in efficiency at the higher powers of around 40 ft/lbs. Only a few percentage drop in # of shots I think. At significantly lower power, it looks it then becomes more efficient than the .25. This makes the .22 an...
