AAC Evolution 45 Suppressor




Advanced Armament Silencers

Manufacturer Number:
45 ACP
Unit of Measure:
Class 3


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. The EVOLUTION-45 delivers flawless semi-automatic operation with traditionally recalcitrant Browning inspired designs from Glock, Heckler & Koch, Sig Sauer, and Walther.

The EVOLUTION-45 is delivered with a comprehensive operators manual, takedown tool, and one Nielsen Device piston assembly. Additional piston assemblies are available in .578-28, M16x1LH, M16x1RH threads so that operators may use their EVOLUTION-45 on a variety of .45 host firearms. Once again, the EVOLUTION-45 is simply the worlds most efficient, high performance, recoil assisted .45ACP silencer.
