M5 Complete Upper w/ 16" .308 Mid-Length Barrel, Adjustable Gas Block & 15" S-ONE Handguard - Anodized Black

The S-ONE handguards are designed with size and weight in mind, featuring a Front and rear picatinny rail which provides plenty of real-estate to accommodate any attachment needs the end user may have. Our proprietary attachment system is a durable and dependable mounting platform, maintaining a slim profile while still providing the strength and stability customers have grown to love from Aero Precision handguards.

NOTE: This complete upper features an adjustable gas block (AGB) that allows the user to finely regulate the gas flow into the gas system. This customization helps optimize cycling performance, reducing recoil and enhancing overall control.
