Aero Precision AR-15 M4E1 Upper Receiver + Quantum Free Float Handguard Combo Set
The state of the art M4E1 platform starts with the M4E1 Upper Receiver. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Since the rail mounting surface and upper are of the same forging, not only is it a stronger system, but it also provides for easy installation of the gas tube with a pre-aligned gas tube hole. Additional lightening cuts save weight and allow for more efficient cooling.
The Quantum free float rail features a lightweight design with 8 different angles for mounting accessories.
Easy barrel installation - Simply insert your barrel assembly into the M4E1 upper and tighten it using the provided barrel nut and wrench. Then slide your rail on and tighten the screws. Within minutes you have a modular, free-floated rail.
