American Tactical Milsport AR-15 Complete Upper 5.56 16" 15" M-LOK

American Tactical AR-15 Complete Upper Features The American Tactical AR-15 Complete Upper is chambered for 5.56 and .223 Rem built around a 16 barrel with a 1-in-8 twist rate that stabilizes a wide range of bullet weights for versatile shooting. The barrel is finished in black nitride for corrosion resistance and comes threaded 1/2x28 to accept a flash hider compensator or suppressor. A phosphate coated bolt carrier group and a micro low profile gas block come fully assembled so the upper is ready to run as soon as it is mated to a lower receiver. A 7075-T6 aluminum upper receiver houses the assembly for a strong lightweight foundation. A 15 free-float M-LOK handguard surrounds the barrel giving builders room to mount lights grips or bipods without disturbing barrel harmonics. Poly flip-up front and rear sights ship installed providing a usable backup sighting system right out of the box. This upper is compatible with any mil-spec lower receiver or parts making it a straightforward option for a new build or an upgrade to an existing rifle. The American Tactical AR-15 Complete Upper for sale at ARMSAGORA gives builders a finished ready-to-mount upper assembly without the need to source and fit individual parts.
