Aero Precision M4E1-T Barreled Upper Receiver 5.56x45mm NATO 12.5" Government Contour Barrel 11.4" Mod4 Handguard Olive Drab Green

This Aero Precision M4E1-T Upper includes the Minimal Optical Deflection (MOD) 4 Handguard. The MOD 4 handguard seamlessly blends robust construction with an ergonomic form factor, ensuring no compromises between the two. Machined from 6061-T6 aluminum, the handguard is engineered with a focus on stiffness to drastically reduce deflection under load. It attaches to the upper receiver via a steel barrel nut, which also serves to significantly reduce point-of-impact shift when using an infrared laser aiming device under load. A 7 sided M-LOK interface allows the user to customize their handguard to their exact specifications and needs. Lastly, each of the 4 QD sockets on the MOD 4 utilize a steel liner to ensure a higher shear load and longer service life with the continued use of QD swivels.
