Aero Precision M5 Barreled AR-10 Upper Receiver - 6.5 Creedmoor - 20" - SS Rifle Length - S-ONE 15"

The Aero Precision M5 Barreled AR-10 Upper Receiver combines an M5 upper receiver for the .308 platform, designed to accept standard AR-308 (DPMS-pattern) components with a 20-inch 6.5 Creedmoor stainless steel rifle-length barrel and a 15-inch ATLAS S-ONE handguard, ready for a bolt carrier group and charging handle.

Features:

• 20-inch 6.5 Creedmoor stainless steel rifle-length barrel
• 15-inch ATLAS S-ONE handguard
• M5 upper receiver for standard AR-308 components
• Low-profile gas block and gas tube installed
• Forward assist and port door installed
• Comes assembled; no bolt carrier group or charging handle included
• AR-10 platform with standard mil-spec fit
• Black anodized finish

The ATLAS S-ONE handguard uses two mirrored, tapered locking nuts for evenly distributed clamping pressure, with front and rear Picatinny rail sections and the center of the top rail eliminated to save weight. The rifle-length gas system gives a gentler recoil impulse and smoother cycling.

The barrel is machined for 6.5 Creedmoor builds on standard AR-308 parts. This assembled upper saves you the work of fitting a barrel, gas system, and handguard, so you only need to add a bolt carrier group, a charging handle, and a muzzle device if one is not included.

Aero Precision brings aerospace-grade manufacturing standards to every receiver, barrel, and small part it builds, so components fit together without extra bench work.
