Mac90 threading

[Dirtball]

Anyone know an indiana gunsmith that can thread an Ak correctly without removing the barrel?

Sorry double post

The right way will require removing the barrel.

Muzzle threading can be done easily with only the front sight block needing to be removed.

Thread alignment tool to start die and someone or a good vise to hold the rifle steady is all that is needed after removing sight assembly.

Is this for a brake or a suppressor? Probably fine for a brake but if you want to run a suppressor, the threads should be cut on centers with a lathe, not a die.

They only right & correct way to cut threads, is to screw cut the tread on a lathe. A button die is good for chasing the threads, but not cutting a new thread. To many changes something goes wrong, start the thread off, a crooked can, bullet will stri,strike, the can...., cut under size, cut over sized, barrel is hardened steal and the thread doesn't cut , it tears, you screw up the crown

Good point, the OP doesn't say.

If it's in good shape, I wouldn't modify it anyway. I have a superb post ban mak90 with the original box and accessories that I would love to put an optic on but I don't want to drill out the pins.

As a master machinist that makes by butt pucker....so many ways to F up a rifle.
Every body who even thinks they saw a video of a guy doing.....can call themselves a "gunsmith ", a gun plumber at best, but I say Bubba.....friends please don't try with any rifle

Depending on the MAK90 you may be able to thread 14x1 lfht but some were taken down to where you could still thread it but by 1/2x28 thread and you can get muzzlenuts or slant breaks over at the AK files with that thread pattern.
