Aero Precision M4E1-T 6.5 Grendel Features
The M4E1 upper receiver brings billet-style aesthetics and enhanced functionality to your build. Its precision forging blends seamlessly with Aero’s ATLAS handguards, and features like M4 feedramps, laser-engraved T-marks, and a port door with forward assist pre-installed elevate both form and function. The included ATLAS R-ONE handguard offers a lightweight, rigid design with QD sling sockets at the 3, 6, and 9 o’clock positions, a continuous Picatinny top rail, and M-LOK compatibility, making it ideal for modern tactical and competition builds.
The 6.5 Grendel 20-inch barrel is made from 416R stainless steel with a DMR profile, rifle-length gas system, and a 1:8 twist rate optimized for a wide range of bullet weights. The 5/8×24 threaded muzzle is fitted with a standard A2-style flash hider, and the barrel has undergone HP and MPI testing to ensure performance under pressure. Please note: this assembly does not include a BCG or charging handle, and requires a 6.5 Grendel bolt and magazine for proper function.
