We at Liberty have designed the most versatile 45 ACP pistol suppressor available. This unit can be used on several different calibers which include all the ones that the Mystic X is rated for as well as the list shown below. The Cosmic is also backwards compatible with all the mounting solutions we already have in place. Give your dealer a call today to get yours! By using our new bi-directional baffle technology, this suppressor is able to use a stainless steel core and be lighter in weight at the same time.
