AR15 Uppers
AR-15 complete uppers let you change calibers, barrel lengths, or configurations without touching the lower receiver. Assembled options drop directly onto any mil-spec lower — stripped uppers give you the starting point for a custom build. Common configurations include 16″ 5.56 carbines, 18″ .223 Wylde precision uppers, 7.5″–10.5″ .300 Blackout pistol uppers, and 6.5 Grendel or 6 ARC long-range builds. Aero Precision, BCM, Daniel Defense, and Anderson Manufacturing all ship complete upper assemblies ready to run.
