Finally got the video done, not very exciting as it all happens inside. Used a 20 round short magazine, have a 40 and a 50 as well. I can see why some people like the bullpup style, with the barrel extension on it is perfectly balanced at the grip, really nice to shoot from the sholder. Pleased with how this one turned out :D

Hi, i've just been looking at your FAR2017 again, do you have your main and air chambers connected?

Yes, mainly to increase the volume, I use it with the air supply always connected but only through a 4mm airline, so it tops up the chamber between shots.

Hi F1...have been reading your thread again, and noticed with your 1" chamber you said you split it into 2..?

What does that do?
