read Barrels - F.A.Q.
for help. good companies to look at are CP, DYE, J&J, Lapco, and Smart Parts. good barrels should not cost more than $60. no need to look at the $90+ ones. you will not get any more performance. although, a multiple barrel bore "kit" is nice to have that i can see spending over $100. except for the flat line, there is no
barrel that will have better range or accuracy over another barrel. the best length should be between 12" and 14". anything longer and you use more gas. a good Paint
match helps with accuracy and range.
