From the manufacturer
Aero Precision M4E1-T PRO CHF M4 5.56mm 13.9 inch Complete Upper Receiver Hanson Mid Length 1-7 Twist A2 Birdcage Anodized Black. 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.
