Aero Precision M4E1 Enhanced Assembled Upper Receiver - Lagoon Blue Anodized - APAR600593AC

Aero Precision APAR600593AC: Aero Precision's state of the art M4E1 platform starts here, with the M4E1 Upper Receiver. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superior engineering, we have condensed the parts needed to mount a free-floated handguard to a mere 8 screws. Since the handguard mounting surface and upper are of the same forging, not only is it a stronger system, but we are able to make additional lightening cuts to save weight and allow for more efficient cooling.

Ease of installation - Simply insert your barrel assembly into the M4E1 upper, tighten it using the provided barrel nut and wrench, slide your rail on and tighten the rail screws. Within minutes you have a modular, free-floated rail.

This shade of anodized blue is subdued, low profile, and provides a slight contrast variation when compared to the traditional black anodized that has become standard today. This finish provides a muted blue finish that still provides functionality while providing a unique look to make your next build standout from the rest!
