Custom Products Barrel Back

This barrel back is designed for specific marker threading. You must ensure the threading on this component matches your marker's breech before purchasing, as it is not a universal fit.

No, this component is designed to be paired with a corresponding Custom Products front section. It is not guaranteed to be compatible with barrel fronts from other manufacturers or different product lines.

The 0.689 bore is a standard, versatile diameter intended to accommodate a wide range of modern paintballs. It offers a balanced fit that helps maintain consistent velocity and accuracy for general recreational and competitive play.

Because this is an older, out-of-production component, you should inspect the threads for any wear or debris before installation. Keep the aluminum clean and dry after use to preserve the polished chrome finish and ensure the threads remain smooth.

A two-piece system allows you to swap out the front or back sections to adjust for different paint sizes or aesthetic preferences without replacing the entire barrel. It provides greater modularity and is generally easier to clean if a ball breaks inside the barrel.
