Thread: Eccentric over barrel rifle suppressors - anyone know?

Some dude out there did experiments with simply hacksawing a new hunting rifle one inch at a time and shooting the rough end with only obvious burrs removed, no effect detected on accuracy. Anyway, if you use a drill with more of an angle on the cutting edges it's self centering.

I have an alternative idea taken from overbarrel silencers, where a barrel protector sleeve is often added. You can extend that sleeve forward of the muzzle right to/through the front of the silencer and perforate it to your heart's content. A small barrel counterbore of 2 inches can still be done, with side venting ports, and the sleeve can be perforated over those ports. Baffles can be welded to the sleeve if desired.

Both solutions seek to address @gundoc's stated/hated no. 1 problem with eccentric suppressors - alignment.

Mine drilled pretty straight with a plain old jobber drill, its probably easier to build than the drawing above
