nine ball gasrouter umarex glock 2 stkHere we have a smart little gas router for your magazine on your Umarex Glock. The gas router here from Laylax Nine Ball is actually both a simple and effective upgrade. It upgrades the gas channel itself from the magazine to the gun so that the gas comes up better and more aerodynamically into your gun. In addition, it is made of a material that can better handle the cold from the gas, so that the valve itself does not freeze This also minimizes gas
