There are more reasons for having the correct bore barrel that just stopping balls rolling out. A very wide bore barrel (comparative to the paint) allows air to pass round the paint in the barrel which affects velocity (and therefore air consumption) and accuracy. And one day you may find the paint is too big for your standard (non-Freak type) barrel.Originally posted by Mr_Toads_Wild_Ride
if u get a nice barrel to paint match plus cause the breech has dual barrel detents u wont get any balls roll out if the bore is smaller then the barrel
try the stock barrel before u spend any money on a aftermarket barrel
