Just purchased this and didnt realize the muzzle threads are milled off. Any options to thread this?

May not be enough metal left to cut threads. Even if you do, it would be small enough at that point that you’d catch hell finding a 7.62 muzzle device to fit the new threads. I assumed it’s 7.62x39mm.
Measure the ID, subtract bore, divide by 2. That’ll give you the barrel wall thickness.
Sleeving it, then threading the sleeve, is an option.
Of course, there’s re-barrel.

I've thought about maybe threading to 1/2x28 then adding a shoulder less threaded sleeve to bring it back up to 5/8x24. It is a 7.62x39, so wall thickness would be a little thin. I'm not sure what would be the best way to keep the threaded sleeve in place would be. Maybe something like locate 620 or silver solder?
Looks like that may be the direction I go.
I would thread whats left at 40 tpi and then make a new bushing in whatever tpi you want.
Letting us know the diameter of what's left would help a lot!
Depending on what you have left you might be able to thread it.
Could push the front sight block back half an inch and cut and rethread. Probably still over 16 inches, worse case in whatever device you want on it.

Saw this after I started working on it.
Ended up 1/2x28 with a threaded sleeve to bring to 5/8x28. I plane on adding the detent back to the front sight and getting rid of the crush washer but it works until the parts come in the mail.
Could also leave it 1/2x28 and run 9mm muzzle devices.
