I've been on a quest to make a lower power 25 caliber carbine and was waiting for the kral nish to come out in the wood stock. Really dig a thumbhole stock, but just couldn't justify another 400 bucks on basically the same gun as a mega when I already have a mega.
Ended up getting an np03 tube from Gizmo and an np01 barrel from Ramen at Canada Shooting Supply. Pulled off the 280cc regulated tube and np03 16" barrel and should kit.
Its pretty short, the Troy Hammer air stripper doesnt even clear the barrel band.
I had another NP03 shroud laying around that the threaded rear end had cracked off so I just ground off the threads on the rear mount bushing, tapped a hole thru for a set screw, and drilled a hole in the shroud. Fits 4 Mrod baffles in front of the shroud. Ended up just under 34" end to end.
I'm happy with the size and weight is more centered, but still a porker even with the 4x32 scope on it.
On to performance. I knew it wouldn't be stellar right out the gate. Also, the barrel leade didnt like any JSB pellets and wouldnt strip off the first pellet on a mag and would get weird toward the end of the mag. These mags were from my jumbo so i know theyre good. Got it to load and shoot baracuda and surprisingly Eunjin 43.2s Power was hovering at 24-25 fpe with the spring just shy of coil bind.
JSBs were doing about 660 fps. I was hoping to get 30 fpe, so I bled it down and tore it apart.
Stock ports were in the .150" range so I ran them all up to .180" and smoothed out the edges and polished up the leade since the barrel was out.
Got it all back together and filled to 220bar. Loaded a mag of Kings and they finally cycled smooth. Guess the finish on the rear of the barrel was catching the pellets.
First shot across the chrony registered 708 so I thought damn, not much gain but it's something. Next shot was 723. Not bad... climbed to 735 by end of 1st 10 shots. Peaked at 743, stayed in the 735-740 range for 25 more shots, and was down to 680s by end of fourth mag. So it'll be a 30 shot gun I'm good with that. I'm hovering just under that 30 fpe mark so I'm sure I'll get there.
Next will be accuracy test and better pics.
