This is a preliminary build of my G&G SG 550, meaning there are still upgrades to be done to the gun. At this point, it is a 90% custom gearbox, but I need to replace some compression parts (under-volume), the gearbox shell (I don't trust G&G's gearbox shells), and possibly a spring (low fps). I will make a detailed video on this gun eventually, but I need to get the rest of the parts first (who knew airsoft parts were so expensive?). In the end, just keep in mind that this isn't the final state of the gun, I only wanted to get a video of it out there.
If you have any questions, let me know.
Thanks for watching.
