Mount is SOLD! Thanks guys!
I will get pics up tomorrow, but this is for a new, never mounted, out of package, no crush washer included 51T AAC Blackout FH.
Bought this recently (as described above) off a forum member, but I've decided to go another route.
Price is $70 shipped! Just trying to get what I paid for it, so price is firm!
Whatever method of payment you prefer is fine by me.
