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:

1. BCM Forged Upper Receiver Assembly, AR/M4 - ejection port cover included as well​

2. Douglas SPR Profile Barrel, 5.56 NATO CLE chamber, 1:7 twist - 1/2-28 muzzle threads - yes it will fit AEM5/OCM5 suppressor and AE brake/collar
