improving an M3 shotgun
Hello ladies!
my question is: how would you improve a standard M3 shotgun / TM copy ?
I know there aren't any upgrades available for them anymore (are there?) in stock anywhere, so I was wondering if that would be possible to get springs for the shottie from some spring manufacturer? (right diameter/length, a bit more power)
(I'm talking about a light increase in velocity from the very low fps they got in standard version with .25)
also, is there any possibility of using tight bore barrels on them, possibly with some adaptations ?
thanks all.
