The Combat Application Technologies CAT/BEN is a subcompact “micro” rimfire silencer that exhibits enhanced performance characteristics for its size, including on short-barrel semiautomatic pistols with subsonic ammunition.  It is rated for 5.7x28mm, and is only 4.28 inches long.  At the time of evaluation, there have been no other rimfire silencers in the public research pedigree that exhibit the performance of the CAT BEN in the same length envelope in this combustion regime.  The silencer is sealed; its monolithic DMLS titanium body may be cleaned with a variety of chemical solutions.

How would the CAT BEN perform on your .22 semiautomatic pistol?
