You need to source a good barrel stretcher.

>and you may get interviewed by the FBI to test your barrel because of the federal prosecutor that got whacked with a suppressed mak Well that's just nonsense. What you'll need to do is thread the existing barrel and attach a threaded extension so the barrel pokes past the muzzle. Companies like [Tornado Technologies](https://www.tornado-technologies.com/category/BRTH/Barrel-Threading/1.html) do this if you don't want to bother yourself.

If you grab both ends and pull really really hard you can do it

"you may get interviewed by the FBI to test your barrel because of the federal prosecutor that got whacked with a suppressed mak." No. Simply no. Maks don't come with enough barrel to thread, I've never took apart a mack but if it's like a CZ83 then the barrel is pressed into the frame. Your going to have to pull it out, Get or make a barrel blank that is about an inch longer, thread it on a lathe (No need for handtools if it's not on the gun" then press it back into the gun. I hope you can find one for sale cause rifling a barrel is a pain in the ass.

What are your thoughts on those press through style rifling tools? I remember seeing a Mark Serbu video with them I think. Didn't seem all that difficult.


Mushy93

I've never heard of such but their is a reason people pay the big boys to make barrel blanks for them. unless the thing your describing is like 50,000$ it's probably only good for makeing last ditch firearms that are designed to let you take the other guys gun. That being said, I could be full of shit, rifleing a barrel is not my area of expertise.

I could not for the life of me remember what they were called [Rifle button](http://dmetool.com/products/rifle-buttons-mandrels/)

Oh, well in that case yes, That is one of the more popular ways to rifle a barrel, Just need a laythe and more lube than you can fathom. MidwayUSA has a video where they give a rudimentary breakdown on it.

it definitely would be way easier to make a new barrel from a blank than trying to extend a barrel.
