Project MAC Part 2: Tapping My Airsoft MAC-11 GBB Machine Pistol For HPA (Airsoft Build Diary)

Welcome back to Project MAC, this time I'm plumbing this WELL MAC-11 GBB Machine pistol for HPA in an attempt to make this gun more reliable and flexible. The biggest problem I face with this #airsoft machine pistol is that there is only a few days in the year which are warm and dry enough (at least in the UK) for this gun to work properly. One key problem is that this gun is not designed for high pressure gasses such as black gas or CO2. Using these gasses will damage it (already blew it up once with Guarder black) and therefore you can only get away with green gas which doesn't cut it once it gets a little cold and damp.

To get around this problem I bought some bits to allow me to connect the Mancraft regulator that we use with the Striker build to my airsoft MAC-11. This will allow me to use this #mac-11 all year round, come rain, sleet or snow. To do this I could've used fill valve adapters which screw into the mag base, the adapters cost £20 each and there is a million and one different types (I don't know what mine would use) and to top it all off I didn't want the airline bent at an awkward angle as this would make reconnecting much more difficult. Instead I bought some flexible tubing adapters and tapped them for a different thread, tapped a hole in the rear of the mag and then screwed the adapters in. This will work just as well as the proper taps although I am unsure how robust the connections are (haven't heard of anyone blowing themselves up doing this though, do this at your own risk) and only time will tell, but so far they work fine.

Again, these build diary videos might be a little more informal than my usual videos, but I hope they help nonetheless!
