Selling this upper I assembled myself and moving onto 6mm ARC. Barrel still has plenty of life left in it. Estimated round count 1,500-2,000 rounds.
I have shot both IMI 77gr Razorcore and my own factory Handloads to mimic MK262 ammo. It reliably groups 3/4 - 1 MOA with factory ammo. I got slightly better accuracy out of my reloads. Only selling to move onto 6MM ARC. I sold all of my 223 Remington reloading equipment, and no longer shoot factory ammo. Therefore I have no use for this upper. Barrel extension was properly bedded into upper receiver with Loctite 620 as shown in Criterion's 'Accurizing the AR-15" video as well as lapping the receiver face.
What's included:

Not included:
-Muzzle Brake
-Gas block
-Gas tube
Okay Industries Surefeed 20 round USGI Steel magazines
(3) gray and (3) black available
I'd like to get $400 for the upper, $20 per magazine
