McGowen Precision AR-15 6-ARC build

[Troy fairweather]

Cancelled my order for this barrel today - I’ll pay the restocking fee if it comes to it.

Aborted the mission before sending a round down range.

Reason: Hornady’s Gas Gun Load data and their proposed velocities -

The odin works barrels use mcgowen blanks, I have. 21" on its way
