Your rifle’s handguard is one of its most important components that can significantly impact its ergonomics, modularity, and aesthetics. The B5 Systems Drop-In M-LOK Carbine Handguard perfectly combines modern modularity with a more classic AR appearance.

Classic Look with Modern Modularity

Unlike most aluminum quad rails and handguards, The B5 Systems Drop-In M-LOK Carbine Handguard has a classic polymer construction. However, it does incorporate an aluminum heat shield inside the handguard for better heat dissipation and to prevent your support hand from getting too hot.

Modularity at Its Best

This versatile handguard can fit both round and triangle handguard caps. It is designed for ARs with a carbine-length gas system. As far as modularity is concerned, this handguard has M-LOK slots on all sides. These M-LOK slots offer mounting options for accessories such as lights, lasers, foregrips, and bi-pods.

One of the best features of this handguard is its classic appearance. It is available in multiple colors, including black, flat dark earth, and OD green, and it can greatly enhance the aesthetics of your rifle.
