G&G F2000 Hop Up Upgrade Research I have been in the lab for the past few weeks trying some prototype designs to bring hop up changes to the F2000. Originally, I was going to modify the gun to accept standard hop ups, but I put in a lot of extra effort to make this upgrade a non mod type 5 second swap. You can literally go back to a stock hop up in that little time, so you don't have to be a tech to have a quality hop up in your F2000. No saw blades, no sanding, no nothing. I'm going to be making this available as a drop in kit sometime in the future. For the meanwhile, here is some preliminary video of my V3 beta working. My final version is already complete, and it's leagues better than what I had in the video. If anyone is interested, let me know! It will help me knowing how I can scale this, whether I make it on a CNC or keep it as is made out of carbon fiber. I got a video of this working, taking the gun airsofting to Gamepod in Antioch this weekend to do the final testing.
