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.
This barrel takes our long .650 OD Thermal Dissipator (JPTD750L).
Note that the Orange Fade Thermal Dissipator is made to order and will add two weeks to delivery.
Due to the extreme demand of this new caliber, there is a very limited supply of barrels. New orders will likely be fulfilled in September to early Q4.
