5.7 Barrel for 3D AWCY? prints 3DP90 / XM5.7

5.7×28 barrels finished with black nitride for various 3d prints from AWCY? Currently the 3DP90 and XM5.7(beta)  use these. They have a 1/2-28 Thread .625in long. They also have wrench flats on the side near the chamber to make installation easier.

Standard barrels will come in the finned configuration for reduced weight. The Diamond pattern was designed by V8 and does the same and adds some front to back air flow.

They are for different guns the 8in should not be used in the P90 as the muzzle will exit inside of the print.
