M4E1 Threaded Complete Upper, 11.5" 5.56 Carbine-Length Gov Profile w/ 10.6" MOD 4 Handguard (BLEM)

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.
