To satisfy the requirements of a major U.S. Military Anti-Terrorist unit, AAC has made a number of improvements to the EVOLUTION-9 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. The EVOLUTION-9 delivers flawless semi-automatic operation with traditionally recalcitrant Browning inspired designs from Glock, Heckler & Koch, Sig Sauer, and Walther. The EVOLUTION-9 is delivered with a comprehensive operators manual, takedown tool, and one Nielsen Device piston assembly. Additional piston assemblies are available in ½-28, ½-32, and M13.5 x 1 LH threads so that operators may use their EVOLUTION-9 on a variety of 9mm host firearms. Once again, the EVOLUTION-9 is simply the worlds most efficient, high performance, recoil assisted 9mm silencer.
