To satisfy the requirements of a major U.S. Military Anti-Terrorist unit, AAC has made a number of improvements to the EVOLUTION-45 silencer. The Nielsen Device is now completely integrated within the 1.25 in diameter, aerospace quality aluminum body, yielding a sleek appearance that belies the fact that this is a recoil assisted design. Improvements to the baffle stack and initial expansion chamber have further reduced first round pop and increased the overall level of sound reduction.
