Quantum Industry Precision Bearing Fire Control OilMost fire control parts are subject to a lot of stress during operation. High-quality trigger oil not only prevents excessive wear, but also eliminates uneven friction, making your trigger feedback more responsive. 4UANTUM SPEED is formulated to maximize It reduces the contact friction between metals, so it is also suitable for gear bearings in electric guns. Its attached pen tip can easily reach the small gap between the teeth, and the permeability of the oil allows it to be used on every surface. Leaves a thin, low-friction protective coating that allows easy oiling and maintenance of fire control parts without completely disassembling them
