Disclaimer: you must be 18 years old and up to buy this air rifle. It is not over 500fps, so no PAL is necessary.
Hi guys, I've hopefully got enough parts for 5 of these Chaser/Rebel pcp pistol/carbine kits with the two barrels. All I have short barrels for is 22 at the moment, so that's what they'll be.
Unfortunately the camo grips got left out of my order so I only have one camo kit, and the rest black. They'll look just like a Chaser, like this for example.
$295 - 7%=$274.35 shipped
If you want one don't expect them to ship til January =). I'll post tuning results as I get them in a review. Thanks Image

Yeah! But perhaps with only the 9" barrel. It'll be a couple months.
Regards,
Wes

Got one built! Unfortunately it's only shooting a high of 360fps so will have to tear it all apart and drill out the valve port hole a bit. These are different than the other valves snowpeak makes in that the valve itself is restricting air, not just the port.

Congrats on the new build..!

Do you have a working example of the Valve to dupe the valve hole size from..?
If so, it would sure save you time over the drill-test, drill-test process...

Good point. I think I'll just drill out the valve poet hole to the same as the cr600w hole size then use the metal transfer port to do the trial and error. I've already got a bunch of those with different hole sizes and it's not hard to swap them out. I'd just use a pr900w valve, but the screw holes are different on the bottom, so it doesn't work.
Shouldn't take long!

Getting closer! Tricky getting just the right port and hammer combo to get a longer string while keeping it legal. I wish I had some more variety of small drill bits. Will have to look somewhere other than Canadian tire =)

Just about time for Princess Auto to be putting their numbered bit sets on sale again.

Not ultimate quality, but most of them seem to work. The tinier bits in this set are too small to chuck up even in a 3/8" chuck. I use mine held in a tool with the work in the drill chuck :mrgreen:

Surprising how close these come to airgun calibers....

Finally getting back to this project again. I see now that it will be a choice of low power pistol shooting at 400fps and long barrel shooting 500fps or staying with the short barrel and tuning it up to close to 500fps. The long barrel is just too long compared to the short barrel and there is a big difference in velocity with the different barrels. (Interestingly, this is more pronounced with air than co2).
Right now I have it shooting in the 440's with the pistol, but putting the long barrel on makes it shoot way over the 500fps limit. If a person only planned pesting or longer range target shooting in carbine mode, then tuning the gun in pistol mode for 400fps for 10 meter shooting would be fine I think. However, if a person wants to use it as a grouse pistol while carrying a rifle hunting deer or something, it'd be better to buy the short barrel only, and just switch from carbine to pistol while keeping the same barrel.
Anyone interested in a specific tune, let me know, and I'll see what I can do.
I'll post a few different shot strings next with different barrels and tunes.
Cheers,
Wes

Well, once I got the proper long barrel on, it helped considerably, lol. I was using a test barrel, only problem it was a CR600W barrel, and those are a couple inches longer, I finally clued in to. Anyway, that really helped bring the velocity closer between the two.
Here's a string of 40 shots with JSB 14.35gr starting at 130 bar and the long Chaser barrel, and ending at 55bar. This is with a cp1 spring and an extra little spring inside it, and a 1/16" transfer port.

(130 bar) 467 465 466 471 468 465 470 475 471 472 475 477 479 482 490 err 484 477 err 486 486 487 490 483 496 490 491 487 492 493 489 490 483 483 481 478 474 471 463 460 55bar

The short barrel was shooting in the mid 440's with air arms 13.43gr pellets, but I'll shoot a new string with the 14.35gr jsb and post that next.

Here's the short barrel string with jsb 14.35gr starting at 135 bar and ending at 70 bar. The shorter barrel shrinks the useable shots quite a bit. Interesting how it works. Still it looks like 4 magazines worth from 130bar to 75 bar or so.
(135bar)400 403 401 411 413 423 415 418 422 423 426 (120bar) 433 426 431 432 425 433 433 433 436 432 432 432 430 430 429 431 err 427 424 425 421 415 412 412 406 (70 bar)

Hey looks cool.
It's a nice kit.
I'd like mine shooting the .25 caliber for sure. Also 495fps with JSBs 25.39grs works
