New beast....the kral puncher breaker

[WHITEFANG]

Well the cat is out of the bag. Yes those guns look good and the prices are good. They do load from the left do they not?
Happy you got one. After we talked about this gun I showed it to a freind. Not sure what he did.

The carbine looked good as well and was much cheapet. As I read after our talk I saw several different possible makers and barrel supplies throw on the mystery of the gun.

As long as it is mechanicaly good a rebarrel is nothing.

Can't wait to see some more reviews of the gun.

Enjoy!!💀 I am doing the 10 meter adventure right now. Lol You never know what I will dive off into next. But I do not waste much time once I set my mind to it.

Sounds like another gun for MH to explore.

CONGRATES BRO!!💀

That's awesome Darren!  Nice rig.  What mods have you started on? 

[Hunt4dinner]

How is the accuracy on this? I emailed pyramyd air and they said they expect preorder in the next week or two and delivery within a couple weeks after. I think I will hold out to see their prices first before I order overseas. Call me old fashioned but if I can keep my money here in the states I'll sure try to. I do like the looks of these things!

Update on the tweaking ...

Darren & I just tore his Punisher Breaker Pup down to it's bare bones today.
Did an inventory of design attributes, weakness's and places to modify for both Unregulated & regulated uses.

So ... being for now Darren choose OEM unregulated we did a bunch of mods and gave the gun a through going over.
All done ... JSB 18.1's easily making 930 FPS !! ( 35 ft lbs +/- )

Interesting day being inside this KRAL action and now know first hand what we have to work with and such required information to tune on them if requested too.

Let me guess: trigger sear shape and lighter trigger springs, port sizes in general and hammer spring to hammer weight tuning?

Lets just say the engineers of the gun are bit removed from the actual manufacturing process  .... LOL engineers  !!!
being guns pretty much a loose splash of MANY manufacturers the blending of a final product while mechanically sound enough needs some fine tuning done.

The primary issue noted was Transfer path .. valve to barrel is a MAJOR up/down spec of sizing differences.
There use of an air arms ball valve type velocity adjuster being the tight spot for modifing the breathing specs, tho as the mono block receiver is manufactured it too somewhat strangles the flow tho modifiable when correct changes applied.

For those who have been around Evanix rainstorms much in basic design is familure there.  Really did not note any absolute SPLASHES in designs, tho much is similar across a few other manufacturers past designs.

For the coin ... yea pretty darn solid !!   Tho there NO Kricket Or Mutant and at less than 1/2 the cost ... No Duh !!
 

[WHITEFANG]

Glad you 2 got togather and got to the total stripping down on what all the design specs are.

I knew after seeing much reading on the gun as it came out.  Darren buying one some good would come forth. Glad you 2 paired up on a tear down.

Oh yes, I forgot the velocity adjuster bar. Probably too small in diameter for .25 porting and thus restricts the power in that caliber. Can you drill the block for larger diameter bar or do you have to remove it and block the sides of the breech?

If I were to go about a full on power mod would drill / ream out the adjuster bore larger, make a new cross pin & then line drill/ bore threw it while installed & get the larger spec and correct alignment issues present in one operation.
We were able to get @ .165" transfer sizing established with what we had  ... And that took a bit of work on every part of the action where transfer passages were.

[oneshot61]

Just curious.. I thought the transfer ports were 4mm from the factory?

Anything stopping from going larger?

Some parts are, others not ... thus the up/down sizing spec comment.
Upper receiver above the adjuster to barrel @ .190"
Velocity Adjuster @ .120"
Lower receiver adjuster to valve @ .150"s ( Don't remember exact at that spot )
Valve & barrel @ .120"

Yup YOYO sizing 

We were able take the .120" specs areas to @ .165" using all the stock parts.

** We could have gone larger EXCEPT at the adjuster which is pretty thin now and the transfer systems tight spot !!

[darren]

So got it sighted in....And began to settle her down.
Well my backstop for sighting in is a 14 inch cast iron skillet...
Well evidently 35 fpe will shatter a skillet....

I completely stripped the factory stock and oil finished it

[WHITEFANG]

Not bad at all on the eyes. So much for cast iron targets.lol👀

MH will get you lined out.💀

Thinking of picking one of these up, about how many shot can You get out of this .22 @ around 23 - 28ish fpe regulated, since I see Huma has one up on there site. I have need of a .22 and I'm feeling the Bullpup fit a lot.

Nice gun Darren.

The Huma reg for the Kral Puncher doesn't look like it has much plenum. I'd be surprised if you could even hit 28 fpe with it.

Nice gun Darren.

Only a WAG based upon previous "Rainstorm" regulator tuning.  With such a large throat valve and poppet just shy of 1/2" diameter ( .490" )
gun is still going to require a fairly healthy hammer strike to open it. The rainstorm had similar air volume so that taken into consideration would be surprised at 30 ft lbs it does any better than 50 shots or so.  I was never able to get the RS to run very efficiently, tho it was rock solid while under regulation.   Tho NEVER doing a Regulated KRAL as of yet ... just a WAG.

.357 Evanixes use only 10.9mm poppets, that's about 0.429". It looks like Kral could easily go to .45 caliber if they sorted out those other things in the air path.

Was just over at HuMa.Com looking at the specs on the Puncher Reg ... states WILL NOT FIT 32mm I.D. Tubes which IIRC is exactly what these NEW Puncher "Breakers" are fitted with ... meaning the Regs likely were / are for the original early version actions

Also looking at its shape ... it really does not match to what I just had hands on just 24 hours or so ago which leaves me further convinced Darrens NEW gun is different

[Prouzy]

How does this predict for the .25, any ideas?
