Need help: Barrel Sleeve

Hello,

I'm building a x25 AK and come to you all with the first of many problems.

I am planning on using a pps43 barrel with a sleeve for this build. I bought a sleeve from lichtenburg research, but it is nowhere close to where it needs to be. The interior diameter is far too small, and the exterior is slightly larger than will fit. This is not to mention the rim on the end of the pps43 barrel (oops!)

Anyway, I don't have the machine power to get this thing to fit around the barrel and into the trunnion. Will anybody be willing to rent out their time to help me with this? I'll pay shipping and am more than willing to compensate you for your efforts.

I need the outside of the sleeve turned to close to .908, and either the inside of the tube needs to be profiled, or the barrel can be turned to fit the tube.

Here's a picture. It pretty much wins the award for worst ever. Hopefully I'll get a better one up soon, as this one is embarrassingly bad.

Thanks for all help, gunco has never let me down in the past.

I can't help but got a suggestion.
Does the flange have to be removed from the barrel?
I was thinking put the sleeve on the barrel from the front and press the flange tight up against it, then have the flange turned down with the sleeve to the size you need.
Just a thought.

Is the flange important? I thought I'd cut from the back, where the barrel would be reinforced by the sleeve, rather than taking material from along the front if the barrel just to get the sleeve to the rear.

I got the barrel from a guy in town for $50

Bohnscot, that's looking pretty nice. I've got a ways to go before I get there. Mines going to be a pps43 barrel on an Egyptian kit with the pps43 magwell...hopefully.

That doesn't mean I can't ask questions though, right?

Where did you get the barrel extension?
What did you do for headspacing?
Which bolt are you using?

no, i enjoy building, learning and sharing . i have a friend that works at a machine shop and has a small shop in his garage and happens to really like corona's, so i filled up a cooler and headed over. he had some seamless tubing that he machined to fit my needs, plus shaved my trunnions for the 1.6mm receiver. i was thinking of using the erie ordnance depot tok bolt, but i will try to mod a bolt from a thread that i cant find again. its milled out at the rotating cuts in the carrier and the bolt is pushed all the way back and welded. it has holes drilled in the tube of the carrier to access firing pin retaining pin.and the nub in back plus bolt stem is cut flush to carrier to allow
bcg to drop in receiver. to set head space i plan on welding a block to the left side of carrier to contact front trunnion to headspace

my guy just trued up the barrel and bored the tubing on the lathe to save taking material off the barrel. once it was pressed on (which he done on his lathe) it was turned for final od. very professional work

Steve you can take the flange off, what I said earlier was just a suggestion.

I think I'm going to open up the sleeve a little and leave the flange in place for strength's sake.

Bohnscot, thanks for the info. I like the saiga look on your rifle, I'm pretty sure I'm going to end up with a saiga forend. I'm going with a shortened gas system, and it'll cover up the shortened system nicely.

I like your muzzle extension. Do you have a link to where you bought it?
