Custom Products Barrel Back Autococker

A 0.682 bore is on the smaller side, which is ideal for tighter paint-to-barrel matching with smaller caliber paintballs. If you use paint that is significantly larger than the bore, you will likely experience barrel breaks; it is best to test your specific paint batch before heading onto the field.

This component uses standard Autococker threading, which is one of the most common thread patterns in paintball. It will fit any marker designed to accept Autococker-threaded barrels, but you should double-check your marker's manual if you are unsure about its specific thread type.

The hand-polished interior reduces friction as the paintball travels through the barrel. Less friction means more consistent velocity and less drag, which helps maintain the ball's trajectory and improves overall shot accuracy.

No, this is a standalone barrel back. You will need to pair it with a compatible Custom Products front section to complete the barrel assembly.

Unlike many stock barrels that are mass-produced with looser tolerances, this unit is manufactured through a nine-step precision process. This results in a more consistent inner diameter and a smoother surface finish, which directly translates to better shot-to-shot consistency.
