CS Airsoft continues with his tech tips with gas blowbacks showing how you can do an upgrade to a Marui gas magazine... "Since Airsoft Gas Blow Back (GBB) magazines from Tokyo Marui have no O-rings installed, I will show you in this Video how to install them by yourself. I hope I was able to help you with this video."
