Item # 163094 Style RPR-APAR712102M2 UPC 840014613366 Condition New Manufacturer [Aero Precision](https://www.kygunco.com/brand/aero-precision) Barrel Length 10.5 in ### AERO PRECISION M4E1-T-NO FA- COMP. UPPER 10.5" 5.56 CARBINE 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 we are able to make additional lightening cuts to save weight and allow for more efficient cooling. #### FEATURES: - M4E1 Enhanced Upper Receiver, No Forward Assist - 9.2" ATLAS S-ONE Handguard - 10.5" 5.56 CMV Barrel - Low Profile Gas Block and Mid-Length Gas Tube - Port Door Assembly - A2 Flash Hider - This complete upper receiver does not include BCG or Charging Handle. #### M4E1 Enhanced, No Forward Assist Upper Receiver Features: - No Forward Assist - Custom enhanced forging that gives the upper receiver a "billet look" while maintaining the structural integrity of a forged part. - Picatinny profile that blends seamlessly with our Enhanced and ATLAS Series Handguards - M4 Feedramps - .250 takedown pin holes #### ATLAS S-ONE Handguard Features: - Front and rear picatinny rail - Eliminated center of top rail for weight reduction - Indexing grooves in 12:00 position for positive grip control - Quick disconnect sling socket at the 3, 6 and 9 o'clock positions - 1.3" Inside diameter - 1.5" Outside diameter - Compatible with mil-spec AR15 upper receivers and barrels - M-LOK attachment points #### 10.5" 5.56 Barrel Features: - 5.56 NATO 10.5" Barrel, 1/7 twist, 4150 CrMoV, QPQ, gas port drilled - .750 gas block journal - Carbine length gas system, .0785 gas port - M4 Feed Ramp Extension - HP and MPI tested - Standard A2 flash hider ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
