Description

This Midnight Edition 10.5″ 5.56 NATO Complete Upper by DBI features a 416R Stainless Medium Profile barrel chambered in 5.56 with a 1:7 twist. The barrel is then finished with Midnight Bronze Cerakote. Built on a top-tier t-marked Forged Upper Receiver and finished with Dirty Bird’s 9.5″ SMRS M-LOK Handguard. No corners are cut when manufacturing these complete uppers. All barrels are dimpled and cold blued, use a black nitride 4140 steel gas block and a stainless steel gas tube. The gas block set screws feature knurled cone tops and are installed using blue locktite ensuring that no amount of vibration will cause the set screws to come loose but they will still be removable for servicing if needed.

This complete upper features an extended latch charging handle (Midnight Bronze latch matches the barrel) and a M16 profile Bolt Carrier Group with a slick and durable DLC (Diamond Like Carbon) finish.
