JTS My bartered for JTS Airacuda Max .22 Build

Jump to latest Follow Reply
Today's goal was to finish the shroud, and it is done.


Not the best work, im using no machine shop tools for any of this, a true diy out of a home owners garage haha.


Anyways, ends are epoxied in, grub screws (m4x.07 stainless) installed and ready to be snugged to the barrel. End cap spray painted.

It's not done but I wanted to bolt everything together after all the work and make sure everything still fit as it should

Just have to thread the barrel, order the tko, and then I'm gunna reseal her , air her up, and let em rip.

Cool project man! I liked my Pre production prototype I got to test. Until I slipped while handling it and essentially made the gun unusable. Was surprisingly nice for what they are.

Thats what I am working with ... Pre-production test rifles. Never seen or even handled one of the official release rifles. For what they are, I'm happy for sure !!

What’s the plan with threading the barrel? Are you going to tackle that on your own or send it out? I worked on a few myself and even the most expensive barrels have off centre bores. Make for a real pain when crowning on a lathe.

I am going to thread it myself with a centering die, by hand. Have been watching quite a lot of videos of guys doing it on PB platforms and it looks promising.

The major thread diameter for 1/2 unf is .50”. The end of that barrel is probably .475”. You are probably going to wind up with some sloppy threads which could lead to clipping.

Mine comes out to .487 (If I remember correctly) , I checked this as well because I had similar thoughts before I even measured, but was going to try and give it a go anyways to see. The only other option I have is a slip on fit from TKO with grub screw attachment.

Obviously I will keep the post updated

The back of the mod is probably going to be nice and square. The only hope is if the step up in diameter on the barrel is square. That would give you some hope with sloppy threads when those two flat surfaces mate up.

Snug slip fit LDC and a couple grub screws ... ;)
Threading barrel will do 1 of two things ?
If done with a DIE it could tighten choke further while also not be done evenly creating a clipping issue.
OR ....
Done via lathe single point have the choke if present open up becoming looser, tho nice true threads.

I was thinking about giving TKO a call to discuss this , giving him my barrel end diameter. I need a 1 inch diameter ldc no matter what anyways.

The internal design of the mod is going to determine if it wants to stay put at 40fpe only attached with grub screws. I would ask TKO. I also know what I would do if you shoot the slip fit across the yard. When you walk over and pick it up and head back into the shop, you have everything you need to make it work. You’ll just have to choose the next step wisely.
