Paintball Barrel Insert FAQs

What do paintball barrel inserts do?

Barrel inserts change the bore size inside the barrel so players can better match paint or projectile diameter for consistency and efficiency.

Are PWR and Freak XL inserts interchangeable?

No. PWR and Freak XL are different insert formats. Match inserts to the barrel back or barrel system you are using.

How do I choose a bore size?

Measure or test your paint size, then choose a bore that supports your desired balance of consistency, efficiency, and reliability.

Paintball Barrel Inserts & Bore Kits

Bore inserts and sizing kits for matching paint, improving consistency, and tuning accuracy.

Bore sizing helps keep air behind the paintball instead of letting it escape around the ball before the shot exits the barrel. A better paint-to-barrel match can improve consistency, reduce wasted air, and help the marker feel more predictable during play.

This collection is built for players using insert-based systems and accuracy-focused barrel setups. Choose barrel inserts and bore kits based on your paint size, barrel platform, and whether you are shooting roundball, First Strike rounds, or a mixed setup.
