Refilling the Huben GK1 5000psi

[TC2Mc]

Is rated for 4500 but filling the huben?

Yeah it’s supposed to be up to 4500psi. But I filled my huben gk1 just fine. The gauge did go into the red for like 1-1.5 mins but it filled it past 35mpa which is a little over 5000 psi. I usually never let my compressor heat past like 42 degrees though. From now on I will probably only fill to 30mpa just to be on the safe side though. But yeah I was surprised!

What about just goin with the AEA 7000psi compressor? These air guns just keep going up in pressure! You think it be wise to just go with the 7000 and skip over the cs4 at 5800?

As per pellet shop there are still some issues with it and aea is working on it. The only ones available now are from out of the country and if you have any problems with them, you have to send it back to that country. It’s going to be an amazing compressor, but I would definitely wait for the revamped model to come out and be available in the states.

I've got to get a different hand pump. I have a vevor but i can't get above 4200 psi with it. I weigh 175, pretty active. I even wore a backpack full of dumbells to get my weight up but no dice. Cannot get the handle to depress once i hit 4200 or so. The pump had a pretty stiff action from the get-go so it may be a bad pump.

Back pack full of dumbells that's the dedication we need

Gx cs3 doing it for now.....

On another note...
I just got the gk1 .25 v3 and it's more tame than v1? it does not get up in the 900's with a 44 gr slug at full power i think the most i was able to get was like 880 fps i think 76 fpe... I see all these videos of people getting 85 fpe i don't see how I get there..
