Just like the title says I am interested in replacing the barrel on my milled Yugo M-70. I know that the Yugo is kind of a beast unto itself for many of it's parts so I need to know if this barrel is the correct size(s) to fit the receiver, rear sight base, gas block, and front sight base. New Manufactured AK47 1970 Barrel Also curious what has been done (or not done) on Green mountain barrels (from those of you who have personally worked one). Like: cut out on chamber end Gas port hole etc. Thanks in advance for your knowledge on these, Nico Wanna kill these ads? We can help!
