I have a VS2 and play woodsball. I am concerned about the overall size, because I need to become really small when hiding. Right now I have the stock barrel (12 inch I think) and it's smooth on the inside. I want a rifled barrel so my paintballs get some spin. I was looking at some hammerheads. I don't think I want anything much longer than 14 inch. Should I get a counter bored muzzle (i.e. a Hammerhead) or something else? What do you think? I am open to any and all suggestions.
