Class III / NFA Item

The Zulu is the culmination of several years of research into building the perfect 556 integral AR15 assembly. We worked on several things such as sound performance, back pressure management, bolt carrier velocity, ejection port noise, accuracy, and many more criteria to bring you the perfect balance of all these items. First we started off with a great base platform by using Aero Precision premium uppers and rails, St. Croix bolt carrier groups, and a custom spec stainless barrels. We have built this silencer system with titanium where possible to keep weight down and Inconel where needed to add great service life to the system. The top off this whole project, the whole thing comes wrapped in a Liberty’s Defense fireproof suppressor heat shield! Call today to get yours!
