Aero Precision .308 Winchester 16" M5 Rifle Build Kit

Aero Precision M5 Barreled Uppers are changing the way you shoot large calibers out of a semi-automatic AR-10 platform. The AR-308 platform is not as plug and play as the AR-15 platform and can be a headache when building a gun from the ground up from different manufacturers. Solve that problem with this Aero Precision M5 Assembled Upper Receiver. This model features a 16” 41V50 Chrome Moly Vanadium heavy barrel chambered in .308 Winchester for affordable long range precision shooting and hunting. Comes with a low profile gas block and mid-length gas system for reliable function. The 15” R-ONE free float handguard features M-LOK attachment slots and the Atlas attachment system is extremely strong while being easy to remove. All you need is a bolt carrier group and charging handle and you have a complete upper receiver group.

This AR-10 M5 upper receiver utilizes the DPMS high profile and comes with forward assist and port door cover installed. It is made from 7075-T6 aluminum forgings and like the handguard, features a black anodized finish. The top picatinny rail features laser engraved T-marks for easy identification of where your preferred optic position. The Aero Precision M5 .308 Barreled Upper is what you need for your next build.
