B5 Systems M-LOK Drop-In Carbine - Drop In Handguard - 7"

The B5 Systems M-LOK Drop-In Carbine Handguard solves the bulk and complexity of factory clamshell designs for AR-15 owners who want a straightforward, field-proven upgrade. Built for reliability-focused carbine builds, this handguard delivers a slim, ergonomic profile with multi-position accessory mounting in a coyote brown finish.

The B5 Systems M-LOK Drop-In Carbine Handguard is a two-piece replacement handguard designed to replace standard clamshell handguards on carbine-length AR-15 platforms without requiring a free-float barrel nut or specialized tools.

The 7-inch composite body keeps weight low while a built-in aluminum heat shield protects your hand during sustained fire. Six sides of M-LOK attachment points let you position a light, grip, or other accessory exactly where it supports your shooting style. The built-in handstop adds a natural reference point for consistent hand placement, while the slim 1.75-inch width reduces the profile compared to standard drop-in designs.

Compatible with both round and triangle handguard caps on standard carbine-length AR-15 platforms, making it a bolt-on solution for the vast majority of mil-spec builds.

Constructed from durable composite material with an integral stamped aluminum heat shield — a combination that manages heat effectively while keeping the overall weight to just 3.90 ounces.

Well-suited for home defense carbines, training rifles, and any AR-15 build where a clean, functional handguard upgrade is the priority without the cost or complexity of a free-float setup.

B5 Systems focuses on function over flash, designing and testing every component to perform under serious use. Their products are a trusted choice for shooters who need equipment that works when it counts.
