For anyone with an unthreaded AK47, I am offering a barrel threading service.
For an unthreaded exposed muzzle AK, the service is $50.
For a shrouded muzzle AK (like a Saiga), the service to cut the shroud down and thread is $75.
This is for standard AK LH 14x1.0 threads. I can install your compensator for no charge if you send it with the gun.
