Well, I'm hardly on aim, but if I am:
Spyder (any blowback clone or not) -
LP, home mods, upgrading, blowback questions - just about anything and everything
Dragun T1 -
clone of T1 (or not - it's almost exactly the same, and the T1 came first - so I know quite a bit.
a little bit - I've fiddled with a few since I've had teammates with them.
just about anything from modifications to electronics (ironic I can't figure out what's going on with my gun right now, though!)
a bit, just need to ask to find out if I know anything about the problem.
I'm learning right now, so I may or may not know the answer.
Eggy, Reloader B, Halo B, Gravity feed and QUANTUM - yeah baby!
A whole lot - just ask!
