I have the proper drill bit from AK-Builder. I have a Romanian with a virgin barrel installed, and I believe the gas port drill bit is designed to drill through the gas port assembly opening at an angle into the barrel. Does anyone know if this hole has to be at an angle, or, can I mark the spot and drill at a 90 degree angle (straight down)?
I am also "thinking" of making a mark on the spot, push back the gas cylinder, use a punch to start the drill and drill a "starter" hole slightly into the barrel. Then replace the gas block assembly to the original position, and complete drilling through the holes in the gas port assembly at an angle. The pre-drilling is to give the angled drill bit a place to "bite into". Does the plan sound OK to anyone that has done it?
I have read where it is smart to "push" a bullet down to the site of the gas port hole to help eliminate the chance of "spurs" inside the barrel when the drill goes though. I am thinking about using a M1 Carbine bullet since is slightly less in diameter that the 7.62x39 bullet. Thoughts?
