GHK M4 BCM 9" Setup (Detailed Build Overview)

Detailing how I built my Airsoft GHK BCM 9" Upper and how I've got it setup. Brand new setup, just tested it recently and it performed well, unfortunately the recoil managed to kill my Z-Bolt LEP (bruh moment, they’re replacing it rn). Hoping to get that Angrygun Sandman S tracer unit in within the next couple weeks; also ordered Rhodesian poo camo paint from Arizona Response Systems to use on my URGI .
