Installation Instructions

Once you have the receiver bushing installed, you will need to check to verify that
the barrel nut is aligned correctly.
1. The barrel nut needs to be tightened and aligned so that a notch in the
barrel nut is perfectly aligned with the opening in the upper receiver for
the drive rod
Note – picture shown with barrel removed for clarity
2. Use the drive rod to make sure that the barrel nut notch and receiver
opening are properly aligned, by placing the striking end of the drive rod
into the upper receiver opening, through the notch in the barrel nut.
The middle of the drive rod cup should be perfectly centered with the
gas port in the barrel.
