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

The B5 Systems M-LOK Drop-In Carbine Handguard in OD Green gives AR-15 builders a rugged, low-profile alternative to the factory clamshell in a field-ready olive drab finish. Built for carbine platforms that demand dependable ergonomics and modular accessory capability without added complexity.

The B5 Systems M-LOK Drop-In Carbine Handguard is a two-piece composite replacement handguard engineered for carbine-length AR-15 platforms, offering M-LOK attachment on six surfaces and a built-in aluminum heat shield.

At 7 inches, the handguard fits standard carbine-length gas systems while the slim diameter and built-in handstop improve weapon handling and keep your support hand in a consistent position. Composite construction keeps the weight low, and the stamped aluminum heat shield protects against barrel heat during extended firing sessions.

Fits both round and triangle handguard caps on standard mil-spec carbine-length AR-15 platforms — no special tools or free-float barrel nut required for installation.

The durable composite body pairs with the integrated aluminum heat shield to balance heat resistance with weight savings, resulting in a handguard that performs reliably without adding unnecessary bulk.

The OD green finish makes this an ideal choice for field-use carbines, duty rifles, and any mil-spec AR build where earth-tone camouflage compatibility is a priority alongside clean, functional ergonomics.

B5 Systems designs products that favor performance over aesthetics, with thorough testing behind every component. Their reputation is built on gear that holds up under hard use.
