Aero Precision M5 Complete Upper, 308 Winchester, 16" Barrel, 1:10 Twist, Rifle Length Gas System, ATLAS S-ONE Handguard, Anodized Finish, Black, Does Not Include BCG or Charging Handle

This AERO PRECISION M5 .308 16in Complete Upper Receiver is a ready addition to any high-quality AR-308 project. The M5 upper receiver comes complete with forward assist and ejection port door, and the Picatinny rail blends seamlessly with the ATLAS R-ONE handguard to produce a truly uninterrupted top rail.

Additionally, the handguard includes QD sling sockets at the 3, 6 and 9 o'clock positions as well as a multitude of M-LOK slots for the optional addition of accessories. This complete upper does not include a bolt carrier group or charging handle, but once you've added those parts as well as a complete lower receiver, you'll be ready to slap steel and punch through paper. Aero Precision are one of the premier names in rifle parts and components, and Aero's complete uppers are yet another example of their dedication to quality.
