ซีลช่องทางแก๊สยาง PTFE สำหรับ Ultra Marui (Gas Route Seal) สีม่วง 30 MWS / M4-1

UpGrade The gas route seal is the join between the magazine you insert and the blowback mechanism of your gun. Both accuracy of its installation, and quality of this route seal are very important to your blowback mechanism function and delivery of the gas out and into the loading nozzle at the correct moment in the blowback function. The ULTRAFORCE version is designed with a slightly harder and lower friction material for a faster air flow but also a more firmer seal with the loading nozzle as it passes and a smoother seal as it moves off it. It has a internal ribbed design to provide a better fit and less leakage.
