Airsoft Guide to Upgrading VFC M4 Gas Blowback

I hope this video helps in one way or another! I'll be reviewing the VFC M16A2 Carbine next. Underneath will be links for most of the upgrades I've talked about. I'll keep it up, Hopefully Youtube doesn't strangle me. These are all Airsoft toy parts, not compatible with any firearms.
