We allow green gas and AEG/AEP's only. All outside guns must chrono at 330 fps or less.
I essentially use a green gas setup. Its just I use a cheaper, more efficient gas like compressed air. Very
easy to handle and replenish. All my systems are fully adjustable so, FPS does not sound like an issue.
Some people just aren't familiar with classic airsoft systems, so I always like to ask before I show up!
Sounds like a great place to network and get some MP5 time in! :lol:
