you think an AMBI Safety would be stock on that lower straight from atrs
Is the Mbus mounted backwards?
If the lower has a built in ambi bolt release, do you still need that tactical link lever?
Ambi safety and a Norgon ambi mag release ARE options that are available at slight additional cost.
The flash hider is not indexed correctly. The "T" should be at top dead center for maximum muzzle control.
Let us know if you need a copy of the installation instructions.
LOL, OP has incorrectly installed his MBUS and flash hider.
NEWB.
What flash hider is that? Does ATRS make it?
