AR-15 5.56/.223 16" stainless steel spiral fluted upper assembly/ 12" Mlok
AR-15 5.56/.223 16" stainless steel spiral fluted tactical upper assembly is designed as an upgrade to your standard AR-15 style rifle. Chambered in 223 Wylde, it may use very similar, but not identical, ammunition calibers: 5.56x45mm NATO and .223 Remington. Offered with 16-inch barrel providing an optimal length for general purpose use in an AR-15 platform, balancing the need for accuracy, velocity and portability. Barrel is made of 416R stainless steel, and is often used for its durability and resistance to corrosion. The spiral fluting is a design feature in which grooves are cut in a spiral pattern around the outside of the barrel. This helps to reduce weight and can also help with heat dissipation, which can help keep the barrel cooler during rapid firing.
