Product Info for Mitchell Defense The DOC AR-15 5.56mm NATO 11.5in Upper Receiver
The Mitchell Defense DOC 11.5in CHF 5.56 NATO Upper Receiver in Black is engineered to deliver optimal performance in a compact tactical configuration. The 7075-T6 billet upper receiver utilizes a thermal-fit barrel seat to improve rigidity and reduce harmonic shift during sustained fire. The cold hammer forged chrome-lined barrel offers superior longevity and thermal stability under heavy use. The ArmorLube Carbon Cutter BCG, paired with a Carpenter 158 HP/MPI bolt, reduces friction and improves long-term reliability. A lightweight M-LOK free-float handguard keeps the system maneuverable while supporting stable accessory mounting.
