So I recently purchased a brand new ASG Bren
Was double firing on an 11.1v lipo and going full auto with a slight trigger pull in semi
Power was around the 280fps mark when it did fire singly
So I gutted it
Fitted a gate titan, 16:1 gears, silent piston head, 3/4 cylinder
Good air seal, good aoe, shimmed correctly
Using a 7.4v lipo
Put in a M105 spring (ASG) I had and it turned out 370fps
Put in a M95 spring (ASG) and it turned out 365fps
Put in a M90 spring (SHS) and it turned out 382 fps
Any suggestions? maybe 1/2 cylinder? I'm at a bit of a loss as it's the lowest power spring I have. Looking for an M80 but having trouble atm
thanks for looking
