Really beginning to become a Kral fan. Put together another frankengun out of an NP-03 and a jumbo bottle gun with an Np-02 12" barrel.
This bad boy is in 25 cal, with an altaros regulator, 350cc aluminum 4500 psi bottle, modified jumbo hammer and spring.
Doing 790s with kings, but I'm running either baracuda 30.86s at 725 fps or eunjin 43.2 points at 655 fps for backyard blasting.
Running a 250 BAR fill, getting 60 shots on the reg.

That looks awesome! I'd love a bottle gun but I'm a hand pumper, so I'll have to buy a compressor first.

Here is a group at 30 yards with the eunjin 43.2s
The bottom is the eunjin 35 domes, not the best lol

Thanks Ed! I'm really digging how this came out. Just needs a little bit more trimming for the fill port and smoothing the edges of the stock I trimmed.
Yeah, I wouldn't dream of hand pumping a bottle gun. I have 3 Kral bottle guns now and wouldn't if I didn't have a compressor and a 3L bottle for remote fills.
Here is the 25 jumbo doing 47 fpe for 40 shots, and the mega marine I made into a bottle gun. Its 177 doing 12 fpe for over 250 shots a fill!

Nice work. Wondering where did you get the biathlon levers?

Thanks Rick... on Pyramyd Air. Theyre the jumbo cocking lever, 25 bucks last time I checked. They fit all the puncher series guns.

Are the bottles carbon fiber or steel?
How heavy did these mods make the NP03?
All three of these Krals look sharp!

The 25 has the original 425cc 3000 psi steel bottle.
The NP-03 has a 350cc 4500 psi thick aluminum bottle but it balances well, the weight sits right in the fore grip where you hold it.
The marine finish one is a 500cc 3000 psi aluminum bottle.

Real happy with my Puncher Auto after a little work invested. 22cal.
Got further plans for it though. As power went up it took a bit to get the timing back. Due that.. mag "sun wheel" out of 7075 since.

Are you running the plenum extension on the np03?

Sweet rig man! I wish they'd import the auto here to the states. I keep my eyes open for one but haven't seen one for sale yet.

Nope, just the altaros regulator between bottle and block. It puts the bottle a little over 2 inches forward from stock.
-
Looks good!
So the bottle drop block is direct fit for replacement of the tube style reservoir on the np03?

It fits the action but you have to inlet the foregrip of the stock a decent amount

Don't let the presence of a bottle dissuade you from a gun if you are a hand pumper - my easiest gun to hand pump is my Air Ranger with a 580cc bottle on it, all because of how it is tuned. The key factors are as follows:
- Power level of shots - more power takes more air
- Shot count - more shots takes more air
- Fill pressure - higher pressure at the end of the fill takes more effort to hit
So if the gun is not regulated, and shoots in a pressure range below 3000 psi, the bottle does not make it harder to fill. Similarly so if regulated too - just because the bottle CAN be filled to 4500 psi does not mean that it has to be filled that high.
Basically, if a gun has a tube and you are OK hand pumping it, switching that exact gun over to a big bottle does not make it harder or less practical if you still use it the same way . . .

Dang that looks sweet :D I was just looking at the NP-02/03 listings this morning.
In the market for a 30-35" hunter , I wish they had a carbine version of the "monarch"

Thanks, I'm happy with it. I was hoping for more power but with a 12" barrel I figure 35-40 fpe is fine. Might try swapping a mega hammer and bigger/stiffer spring and see if it goes up. When I did that with the jumbo it went up 60 fps.
The NP03 can use the 280cc and 330cc tubes from the breaker or Mega guns. Give you a bunch of shots and use longer barrels and shrouds, also huna makes a reg for them.
