Perfect for a new AR-15 build, the ATI MilSport line is compatible with any MilSpec parts or lower receiver you wish to work with. You can drop this upper right onto a complete lower and get right to the shooting range if you wish; it ships with a low profile gas block, flash hider, charging handle, complete bolt carrier group, barrel, and upper receiver assembly fully assembled.

This classic style complete upper-receiver features a handsome 15" MLOK accessory rail, which will give your AR-15 a clean profile while still maintaining versatility and ease-of-use. For high-speed, low-drag builds MLOK works well, but if you only intend to mount irons or an optic on there, this MLOK rail is perfect for that also! 

Do not miss the chance to grab one of these ATI MilSport Complete Uppers, as they will go fast!
