Adjustable Gas Tube System for AR-15 & AR-10 Rifles

This adjustable gas system is installed directly on the gas tube. It provides positive indexing of the adjustment screw for precise and repeatable gas settings for semi-auto AR platform rifles. The system is especially recommended for rifles that become over-gassed when a suppressor is installed. Many standard AR gas systems are not designed to handle suppressor backpressure, which results in excessive gas drive, increases rearward bolt-carrier velocity, and causes additional rifle shake during the firing cycle, ultimately reducing precision. Proper gas regulation directly affects shot consistency and overall accuracy. The system allows the gas flow to be tuned to the minimum amount required for reliable cycling. The adjustment process is simple: close the valve one click at a time until the rifle no longer cycles, then open it one click back. This delivers only the necessary gas flow to the bolt carrier, reducing excess carrier speed and minimizing unwanted barrel disturbance. In pr
