Size

Elevate your shot consistency with CRBN PWR™ Inserts—built for magfed and competitive players who demand precision. Each 8.5" control bore insert is precision-broached and microhoned, then finished in a deep gloss black anodize with laser-etched size markings for quick ID.

A chamfered breech opening and stabilized collar help reduce in-barrel breaks and ensure smooth feeding under pressure. Dial in your bore for air efficiency, changing paint sizes, and weather conditions—then let the insert do the work.

PWR™ is a trademark of Planet Eclipse Ltd.
