Precision bore matching for Planet Eclipse and Inception Designs barrel systems. The Inception Designs PWR Insert Set with Case is a high-performance barrel insert system engineered specifically for Planet Eclipse and Inception Designs PWR-compatible barrels. Designed to deliver the same proven accuracy and gentle paint handling as the Stella system, PWR inserts allow players to fine-tune bore sizing without needing multiple barrel backs. Unlike traditional insert systems, PWR inserts interface directly with a single outer barrel back, letting you match anodizing and aesthetics to your marker while still gaining full bore-sizing flexibility. This design reduces cost, weight, and complexity without sacrificing performance. Each insert features a precision-machined exterior tolerance that locks securely into the barrel back yet removes easily when needed. At the muzzle end, an external chamfer ensures optimal alignment with the barrel front, while the internal radiused ball-entry lip eliminates sharp edges and is exceptionally gentle on paint. Bore sizes are laser-marked for easy identification and can be visually confirmed without removing the insert. Inserts can also be identified by color when viewed through the rear barrel ports. A compact protective case keeps everything organized and field-ready. ⚠️ Compatibility Note: These inserts are designed only for Planet Eclipse and Inception Designs PWR barrel systems. They are not compatible with Freak, Freak XL, or other insert-based barrel systems.
