I've decided to start a sniper rifle project with some spare parts I have been saving for a project such as this one. I have the main body of the "rifle" and I have a scope and pistol grip, and also the barrel. What I need to do is make a very bare bones, delicate stock (think Verpine sniper rifle) for it and I also need to fashion some kind of flash suppressor/muzzle brake for the tip of the muzzle. I'm thinking a piece of pipe a little larger around than the half inch diameter barrel, then drilling out a set of uniformly placed holes over it's entire surface. Anyone have any suggestions that I can use to keep the lines all straight without a drill press and a bad hand? Any other suggestions would be greatly appreciated. Thanks!
