Barrel Finish

This barrel is available with the following finish options:

Machine Finish: Barrel is in its unpolished, "as-machined" state and will show light turning marks and slight imperfections.

Light Polish: Barrel receives a light "brushed" finish. This leaves the surface uniform and removes most machine marks and blemishes.

High-Grade Polish: Barrel is polished to a reflective finish on the same level as our complete rifles and barrel kits.

Black Teflon™: Barrel receives a uniform low-shine black coating.

Heat Sink

This barrel takes our long .750 OD Thermal Dissipator (JPTD750L).

Note that the Orange Fade Thermal Dissipator is made to order and will add two weeks to delivery.
