I am installing an A2 style Front Sight/Gas Block to an AR-15 barrel using taper pins. The holes are to be 1/8 inch (#30). I will drill both the sight base and the barrel simultaneously.
Do I need an end mill bit to be sure that the barrel cuts properly or can it be done with a simple drill? Any recommendation as to the type of drill or end mill I'll need (I have a heavy duty drill press and a machinist's vise). I want to avoid having any possibility of the drill walking when it meets the rounded barrel.
I recognize that the holes will need to be taper reamed when I'm done, but I want the initial drilling to go smoothly.
Any and all advice will be appreciated. I've never done this before, but there's no time like the present to give it a shot.
