Is a longer barrel on paint ball gun more acurate?

Answer 1

this will depend on the paint you are using, good paint that fits one 12" barrel will be very accurate, but a different good paint will be not as good in the same barrel. look into the J&J ceramic though, they are inexpensive and very good barrels that work with most paint

Answer 2

Up to a certain extent. Generally the best accuracy and efficiency is seen between the lengths of 12-16 inches. Anything shorter will not have enough time to accelerate, anything more will use up more air. If you want to use a long barrel (18-21 inches) you MUST use a Bipod or keep the gun completely still and turn the velocity up to get to the required Feet Per Second. If you try to shoot normally with an extra long barrel, the time it spends inside the barrel will actually be affected by the natural shaking of the barrel, costing accuracy.

Answer 3

Theoretically, any high end two piece barrel (12 to 16 inches) with high grade paint, and a good paintball to bore match would be nearly the same accuracy.
