Overview

Designed for shooters who want to reduce signature on a compatible suppressor setup, this closed end cap is intended for use with Abel Company’s Theorem suppressor system. It is supplied as a standard component with every Theorem suppressor and is offered here in a 6.5mm configuration. The cap is made from 6AL4V Grade 5 titanium and finished in DLC/Cerakote, with a length of 0.640". For users building a suppressor setup around the Theorem platform, it provides a purpose-specific replacement or spare part rather than a general-purpose accessory.

Considerations & Trade-offs

  • Designed specifically as a 6.5mm closed end cap, so it is not a universal fit for other calibers.
  • It is a suppressor component rather than a complete suppressor, so it only serves a specific role within the Theorem system.
  • The closed end cap is described as providing maximum signature reduction, which may come with less flexibility than an open-end configuration.
  • Finish is listed as DLC/Cerakote, so appearance and wear characteristics will depend on how the suppressor is used and maintained.
