This Stella barrel back is compatible with the PWR Inserts from Planet Eclipse and Inception Designs. It does not work with other insert systems from other companies.
This barrel back is fully compatible with all Stella Barrel fronts. The new system uses specially designed inserts that maintain all the easy ball entry features of the Stella barrel. This allows the use of a single outer barrel back that can be more cost-effectively matched to the gun and its anodizing yet maintains all Stella barrel performance features AND is available in many sizes.
