Our new Brake Attach (BA) line of silencers is ready. These were developed to meet the needs of customers who require a muzzle device when shooting without the suppressor. We haven't found a "quick mount" on the market that meets our accuracy and repeatability requirements, so we developed the BA series to mount over our brake and provide the same repeatability as our direct thread attach suppressors, like the 30P-1. The 30BA features a conical shoulder for rock solid POI repeatability and to make sure it never comes loose. These use the same baffle stack as their direct thread-attach counterparts (30P-1 and 338P-1) and are just as quiet. The 338BA suppressor can be mounted on the 30BA brake, but the opposite does not fit for safety reasons. The 30BA brake is a single chamber design, while the 338BA brake is a double chamber design.
