Super low power from Kral Puncher Mega
- Thread starter Freddich
- Start date
It was what you said. The barrel had been rotated so the transfer port didn't line up with the hole in it. Carefully rotating the barrel until they were perfectly aligned fixed the issue!

Hey guys! Not sure if yall will see this but i bought the kral arms puncher Np-03 from pyramid air. And its shooting barracuda 18 at low to mid 600fps. I find that odd ? Could of be the Barrel is aligned with the transfer port ? Not sure how to aligned it without out messing it up or hurting my self.
Thanks !
Thanks !

HI I'm having probs with my mega. It's a 25cal should be somewhere between 30-40ftlb.
But using 28gr hunter extremes I'm getting 550fps so about 18ftlb.
Has euro spec spring in.
How do I check tp alignment?

The TP is on the opposite side of the barrel from the set screw indents. Take out the set screws and look through the holes. Does the indent on the barrel match up with the set screw hole? If not, turn the barrel until it does. then reinstall the set screws.

Hi guys.
I'm a little stuck here.
I bought a mega from Spain. Site called tradeinn.
Should be about 38fpe as it's the .25 cal.
I'm getting 550fps with hunter extreme pellets, that's about 18fpe.
I've removed the power adjuster and looks to be 3mm.
It's not losing pressure when in safe.
I'm just stumped
Can anyone assist?
I've spoken to Kral directly and they've been less than useless

Did you adjust the hammer spring tension?
How much does your hammer weigh?
How big is your Transfer port?
How big is your valve port?
Is your barrel lined up with the TP?
My crystal ball subscription ran out.... can't read minds.

Bet it's got a restricted exhaust port on the valve. They do that in Canada and other Euro countries to limit the power or fps.
Take the air tube off and check to see how big the port on the valve is. If it has a tiny hole or a set screw with a tiny hole, then remove set screw. If it's a small port on the valve directly, then you need to degas the air til empty, and removed the back of the tube/valve housing. Open up the valve housing and remove valve and spring. Drill to desired size(within reason... 6mm at the valve is okay). Clean and reassemble the valve and air back up.
Then since it's all apart, take the silly power adjuster out of the side and tap for some set screws. Drill the transfer cavity in the block to match your port on the valve, port the barrel to about 5mm. Get a couple shorter/stiffer springs for the hammer and run a dual spring.
Boom... 60 fpe easy with the right pellet and the rifle length barrel. Run 230-250 BAR for a smoother string.
I get 55 fpe with only a 16" barrel and 5mm ports throughout and a dual spring. I run a 300 BAR bottle though on my jumbo.

that speed make my Puncher Nish in F Version for germany, it pumps out only around 5 Joule at max, the powerwhell in it is only 0,5mm.Hey guys, I'm back after some testing with the chrono. My suspicions were indeed correct, not only does it not perform that well, it performs terribly! I shot 2 whole 12 shot mags of JSB heavies (18.13gr) through it and the average speed was 100,6 m/s, around 300fps from a 200 bar fill.
This means that the output is about 6 joules, or 4.5 foot pounds. Now let's start some real investigating!
with the all open one who has 4mm hole it runs full power like it should.
