Aero Precision APAR640221M4: The upper receiver on this build is our state-of-the-art M4E1 platform. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superior engineering, we have condensed the parts needed to mount a free-floated handguard to a mere 8 screws.

The handguard that accompanies this upper is our Enhanced M-LOK (EM) Handguards provide a lightweight free float design for your custom AR15 build. The M-LOK system allows advanced modularity past the current 1913 Picatinny rail system. Machined to mil-spec dimensions and engineered to perfection, this handguard eliminates bulk while retaining strength and stability. The barrel on this upper is our 10″ .300 Blackout Pistol Barrel is the perfect addition to your AR15 build. Crafted to mil-spec standards from 4150 Chrome Moly Vanadium with a QPQ corrosion-resistant finish, this barrel provides time-tested precision and accuracy for your AR15 .300 Blackout Pistol build.
