The PWR Inserts work with barrels from Planet Eclipse, Inception Designs and Dye Precision that are designed for PWR Inserts. They do not work with other insert barrel systems from other companies.
The new system uses specially designed inserts that maintain all the easy ball entry features of the Stella barrel backs. This allows the use of a single outer barrel back that can be more cost effectively matched to the gun and it's anodizing yet maintains all Stella barrel performance features AND is available in many sizes.
