Thread: Eccentric over barrel rifle suppressors - anyone know?

The only tricky bit with your idea is getting the crown sorted depending on how deep you counter bore it, maybe a brass rod that is a good fit for your hole with the end turned/filed/ground to the same angle as the drill bit and some valve grinding paste. Im not really convinced the baffles in mine do anything but I have a lot of relatively small ports

Yes, prob with long counterbore is keeping it concentric with the bore, or the crown will not be at 90 degrees to the bore either. I think main thing is to counterbore to somewhere where there is good rifling (that is why this rifle is getting chopped), less important to have a beautiful looking crown. 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.
