Builder's Grade Complete 14.5" 5.56 Upper Receiver | 12" M-LOK | With Bolt Carrier Group and Charging Handle
This complete upper receiver may be considered a pistol or SBR upper until a long enough muzzle device is permanently attached, providing a 16-inch Overall Length barrel.
Looking for a high-quality AR upper that is both versatile and reliable? Look no further than our 14.5" upper, which can be pinned and welded to meet the 16" OAL requirement.
This barrel is the perfect choice for those looking for a compact and maneuverable platform in close quarters (CQB) situations. Its shorter length makes it easier to move around corners and through tight spaces, while still providing exceptional accuracy and control.
One of the key advantages of our 14.5" barrel is its improved handling and balance. With a shorter overall length and reduced weight, this barrel is easier to control and maneuver. This can make all the difference in a high-stress shooting scenario, where split-second decisions and precise movements are critical.
The Complete 14.5 inch M-LOK upper receiver comes with a 12 inch free float handguard and is built with only the best Mil-Spec components. The heart of this upper is comprised of a 4150 barrel and our black nitride bolt carrier group that is finished with an incredible polish, making the action smooth and easy to keep clean.
