The Q Speakeasy 7.62mm suppressor is an all-steel .30 caliber can that Q describes as the steel Full Nelson riding on a Quickie mount (brand part no. SIL-SE-QUICKIE-762). It uses a simple baffle design and still ends up quieter than many .30 cal cans, and on subsonic .300 BLK Q calls it the quietest it has heard. Steel means no flash and a lot of durability, so it can be run hard for a long time. It measures 8.5 inches, wears a Melonite finish and, despite being steel, weighs less than the titanium Full Nelson. For a shooter who wants a durable, very quiet .30 cal can without titanium cost, it is an easy choice.
