I do this sort of work, but I only do it in the lathe.
In order to put the barrel in the lathe, I remove the barrel from the trunion.

[kcstott]

You can't cut the barrel down without removing the barrel from the receiver
It will be a SBR if you don't Feloney
Two the headspace will not get fouled up as it is pinned in place.

[ar15barrels]

Moving the front sight back on the barrel without turning the barrel down for the front sight to fit would also be fun.
I suppose you could open up the front sight until it fits on the larger diameter barrel that is left after cutting the barrel shorter...

It's SO much easier just to turn the barrel down to the proper diameter while its already setup in the lathe for threading...

[CSACANNONEER]

Nothing against AR15Barrels. I definitely would trust him to do the work right. But, I believe that Sinister Arms in Thousand Oaks made a special jig to do this without having to remove the barrel from the action. I know that you would be happy with either one's final product.

[CSACANNONEER]

Sinister Arms is an 07FFL. I know he has done some NFA work but, I don't know if he woukd do this or not. Why not call and ask?

[kcstott]

I wouldn't be opposed to going to TO to do this but I was not aware that it would be a sbr/nfa violation even though it would be only temporary for a couple hours while the remaining work was completed.

I guess pressing out and pressing in is what's needed and I'm sure that'll drive the cost up as well.

How much is this going to run me?

Ok lets take a better look at this

One you want the barrel cut down an threaded preferably for 1/2"28 (AR threads) you also wanted the front sight welded to the gas block

Now here's what NEEDS to be done to make this happen the barrel must be removed as it is a SBR violation it doesn't matter how long the barrel is in transition the ATF doesn't care. And since no one here really knows you no one would stick their neck out like that. Two do you really expect someone to try to chuck up on your square receiver and some how or another cut off the barrel and support it to turn it down and thread it. You can just run a die or the barrel from 14mm threads to get 1/2" threads you have to turn the barrel down. and to do that it has to be well supported.

Then the welding of the sight to the gas block that takes time it is a lot of work to clean up and refinish. Gas block should be removed from the barrel and it is why i declined the job because I don't like customers hanging out while I work.
it's just about an all day deal to complete with removing the barrel, removing the parts from the barrel, cutting down and threading the barrel, cutting the front sight and welding to the gas block, cleaning up and shaping the gas block, reinstalling the parts, pinning and welding the brake, Refinishing the barrel and parts either park or paint, and reinstalling the barrel.

Yeah all day and at that point it becomes a T&M thing

AK barrels can be removed and replaced quite easy.

Trying to do all the work you asked by leaving the barrel in place is a royal pain and also set up some violations.

It's also more then you want to spend I can tell you that. $55 per hour $440 for an eight hour day.

I didn't quote you because i knew it would be way more then you would want to spend. That and low post count asking to violate laws didn't give me a warm a fuzz feeling either.

[kcstott]

No it not just post count. It's the whole picture. The questions you ask and how you ask them. Sorry but the gut says no thanks.

For all the work you're asking, the only one i know of that can and would in your area is Randal.
Sorry for giving you a hard time but rephrasing your questions would help.
Like the head space thing on an AK?? We use to build these things by the dozen. Pressing out a pin and barrel to do the work then replacing the barrel and pin will not screw up the head space. And I'm a new guy to building these things. There are people here that have built more AK's then I've seen. Barrel population is done all the time.

[kcstott]

So you ask a question and you don't like the way I answered it? Tough
And this is far from the wood chipper go read through some of my posts on locked threads I can be a real arse hole if I want. This is mild.

And yes I probably do need to get laid or something.

[johnyreb]

So you have a sagia, and your a fan of the current conversions.

I take it cutting the barrel is to get rid of the dimples from the FSB.
And you want the look of the GB/FSB combo.

What I did.

Drilled out the dimples and pulled both FSB and gas block. I ordered a boulton block from Texas shooters supply. I used my sagia gas tube to help install it to make sure it was at the correct spot on the barrel and not canted. I torqued the screws and then I pined it with the pre drilled hole for a guide.

I bought the barrel threading kit for an 14x1lh from CNC warrior, used two wood blocks to hold the gun in a vice and not destroy it, and I slowly and carefully threaded the barrel. I picked up a 14x1lh comp from spikes tactical and a crush washer.

Then I used JB weld to fill in the dimples, sanded flush lightly blasted and cerakoted it and called it good.

And finished with the stock and TWS top cover.

[kcstott]

Nice build.

But now I need to eat some crow. Evolved wasn't the guy I thought he was. My screw up.
Sorry there dude I need to keep better track of user names and pm's

[ar15barrels]

How much is this going to run me?

My pricing for the work is on www.akbarrels.com

You need the barrel removed and reinstalled.
You need the barrel shortened and threaded.
If you want a combo gas block and front sight, you should get that ahead of time as it's not cost effective to re-work the existing parts if you have to pay someone to do it vs. simply buying a Draco type gas block.
Then you need the muzzle device to be perm attached.
My remove and reinstall service covers putting the barrel back on after the perm attach is done.
I do jobs like this while-you-wait so its only one trip.
I would figure on 1.5 hrs.

[ar15barrels]

Is the 1.5 for turning the barrel down and threading 1/2-28 for AR threads or for cut/crown/thread to 14x1 LH AK threads?

It's about the same either way.
I'm about 5 minutes faster doing 1/2-28 threads than 14x1LH because I do 1/2-28 threads daily, buy 14x1LH only a couple times a week...
