The BCM 5.56 NATO Mid-Length AR-15 Barreled Upper is the perfect choice for shooters who demand precision and reliability. The 16″ barrel is made of Mil-Spec steel for increased durability and performance, and features a manganese phosphate finish to protect against corrosion. The 1/7 twist rate is versatile and compatible with heavier 5.56 ammo, making this barreled upper a great option for shooters who want the best of both worlds.

The T-Marked upper receiver is built around the concept of modularity, making it easy to remount tactical accessories as needed. The barrel extension and upper receiver feature a USGI modification that makes the feed ramp longer and steeper for more reliable feeding. These factory machined M4 feed ramps are Mil-Spec and hard coat anodized for durability. If you’re looking for a high-quality barreled upper that will exceed your expectations, look no further than the BCM 5.56 NATO Mid-Length AR-15 Barreled Upper!
