The Harvester by Silencerco is an extremely lightweight silencer capable of handling .30 caliber and smaller rifle cartridges up to .300 Winmag pressures. This silencer has a thinner tube than many and serves excellently on a bolt action hunting rifle without interfering with close-to-bore rifle scopes. This silencer can handle very large rifle calibers but is considered a slow rate-of-fire silencer. Its not ideal for mag dumps or fast paced shooting that would cause extreme silencer heat.  The price quoted is without a direct thread mount.  Mounts with thread pitch of your choice are $82.
