The Tuna Cans Blackfin XL is a full size modular .375 caliber rifle silencer that provides various degrees of subsonic 300 BLK suppression performance based upon the number of baffles the user chooses to install. In the 12-baffle configuration, the silencer is the quietest, though it does exhibit noticeable first round pop (FRP). In the 9-baffle configuration, performance drops somewhat significantly and FRP remains severe. Nonetheless, users may find utility in the silencer due to its economy, modularity, HUB-mount compatibility, and multi-caliber applicability.  Note that although the baffle technology in the Blackfin XL is relatively primitive, this program evaluates its performance in an over-bore condition, which is a performance handicap given this type of technology.

How would the Tuna Cans Blackfin XL in the 12-baffle and 9-baffle configurations perform on your personal defense weapon?
