This upper receiver features the same tried-and-true construction and aesthetics as our M4E1 Enhanced Upper Receivers, without provisions for a forward assist.
The M4E1 Enhanced Upper Receiver is a one-piece design combining the handguard mounting platform with the upper receiver 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.

The description is not clear in that this Enhanced Upper will ONLY fit an Aero Enhanced Handguard. The description has marketing language talking about the superior engineering making it a stronger design and they condensed the parts needed to mount a free-floated handguard... what it SHOULD say is it will ONLY fit an Aero Enhanced hand guard. Ive always had a good experience with 208s customer service and am hopeful they will work with me on a return.
