To owners of F4 Illustrators

[PBfreak01]

Do any of you that own F4 Illustrators have any ball breakedge problems with barrels that have the Prolite threading? (Cause it has that little flange on the inside for the bolt.)

My friend has an F4 and he has a prolite barrel and so far he hasn't had any major ball breakage problems...The only breaks he has had is because of the bore size of his paint
