The only thing better than a .45 is a ZEROED 46 suppressor to put on it. Made to drop the noise level on all .45 caliber or smaller centerfire rifle and pistol cartidges, the ZEROED 46 boasts excellent sound suppression without sacrificing robust build quality in the name of affordability. The nitride finished 17-4 stainless steel construction resists corrosion and finish flaking. The 1/2" square drive front cap and 7/8" wrench flats on the included direct thread mounts allow you to use common hand tools for assembly and disassembly.
