M4E1 PRO Complete Upper 16" 5.56 Hanson Mid-Length CHF w/ 15" MOD 4 Handguard - OD Green Anodized

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.

Breach Charging Handle Features (Optional):

• Ambidextrous Controls: Ergonomically designed 7075 Aluminum levers allow the user to easily charge their firearm with either hand, while remaining low profile and comfortable when slung.
• Robust Construction: Reduced chamfer angles on the 7075 Aluminum reinforced bar design provide a strong foundation for the BREACH? that is resistant to rotational flex or breakage.
• Patent-pending Lever Mechanism: Transfers force-of-use away from the roll pins and into the top/head portion of the reinforced bar protecting the charging handle in the most demanding circumstances.
• Gas Deflection Shelf: Aligns with the upper receiver to redirect gas flow away from the users face when shooting suppressed.
• Functional Design: It is not all just good looks. Stylistic cuts on the charging handle also help to clear stuck on carbon and debris from the upper receiver, while the spacer design seals and protects the lever mechanism from debris.
