This guide details the cleaning and maintenance procedures for Gemtech suppressors, specifically the Aurora II and Lunar models. It covers the use of urethane discs, petroleum jelly packing, and the cleaning of internal components like the Nielsen device. The guide also provides advice on cleaning rifle suppressors, mitigating first-round pop with water or petroleum jelly, and the importance of cleaning mounting surfaces for rimfire suppressors. Safety precautions, such as using appropriate brushes and ensuring firearms are unloaded, are emphasized.
The Gemtech Aurora II is a compact 9mm suppressor, an evolution of a design dating back to the mid-to-late 1990s. Originally conceived for pilots in emergency kits, its unique construction utilizes eight urethane plastic discs coated in petroleum jelly, known as wipes. This design offers a limited lifespan, typically yielding 30-40 rounds before requiring repacking. The suppressor features dual threading, accommodating both 1/2x28 and 13.5x1 metric pitches for increased firearm compatibility.
