BCM® BFH 16" Mid Length (ENHANCED Light Weight) Upper Receiver Group w/ MCMR-13 Handguard Factory BCM upper with BCM BCG, BCM QD Sling mount, and one 5 slot picatinny rail piece. Upper has the cold hammer forged BCM 16" ELW barrel profile which is chrome lined. If you prefer the KMR BCM rail (keymod version) I can switch out the rail for that as well. Barrel has BCM gunfighter comp from factory. Upper has less than 3000 rounds through it but for the quality of barrel and BCG this comes with, that is not a lot of rounds. Never had a malfunction with this upper. Shot great on a colt lower. Uppers are $959 new from BCM.
