AERO M4E1-T PRO UPPER RECEIVER GROUP 16 ODG

This complete upper includes our 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. - INCLUDES: - M4E1 Threaded Upper Receiver - MOD 4 15 Handguard - 16
