This complete 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 was designed with additional lightening cuts to save weight and allow for more efficient cooling.
Includes:
- M4E1 Enhanced Upper Receiver finished in MTC Dark. Upper receiver is assembled and includes the forward assist, dust cover and barrel nut.
- 15″ Enhanced Gen 2 M-LOK Handguard finished in MTC Dark
- M4E1 Lower Receiver finished in MTC Dark
*Limited inventory, MTC Dark M4 builder sets are a limited time run for the month of November 2022.
