[QUOTE="Canadian Bushman, post: 1460464, member: 41122"] Few things ive learned from building suppressors. Weight of the suppressor will nearly always move POI down. How much is dependant on weight of the supressor and rigidity of the barrel. If the supressor is concentric, has a rigid attachment, and indexes to the same position when attached. It will repeat its zero. I dont think anyone can assure better accuracy with a suppressor, but the odds of accuracy getting better with a supressor are pretty good. The weight at the end of the barrel slows harmonics, and the blast baffle diverts turbulent air that can otherwise disrupt a bullets initial release. If your load is sensitive or tuned near the edge of its node, a supressor can knock it out as easily as it can bring it in. Supressors do not increase barrel pressure, however they do increase the amount of time the bore is under pressure because they are capturing and slowing escaping gases. Very similar to having a longer barrel. This is most evident in gas operated weapons where the gas system will remain pressured longer increasing energy of the reciprocating parts. [/QUOTE]
