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.
