Thread: Eccentric over barrel rifle suppressors - anyone know?

I have made a few eccentric screw-on suppressors. They are a pain in the arse to make in comparison with concentric units, and the only major advantage they offer is the ability to use iron sights. They do give a slightly better suppression performance because of the inconsistent gas flow. The best eccentric design I have made in terms of performance and suppression is of rectangular cross-section, giving a greater internal volume than a cylindrical unit of similar dimensions.
