B5 Systems CAR15 Drop In AR-15 Handguard - Carbine Length

The B5 Systems CAR15 Handguard is a drop-in replacement for AR-15 rifles built for shooters who want the classic 6-hole handguard look rather than a modern rail system. This lightweight composite handguard replicates the original CAR15 profile while adding a built-in heat shield factory triangle handguards don't have.

• Original 6-hole CAR15 styling
• Integral heat shield
• Durable composite construction
• Available in black
• Made in the USA

Unlike B5 Systems' M-LOK carbine and mid-length handguards, the CAR15 skips rail slots entirely to preserve the slim, classic silhouette associated with early AR15 rifles and retro builds. It's a drop-in swap for existing triangle or round handguard caps, so retro-style builders can update heat protection and durability without changing the rifle's period-correct look. The composite construction keeps the handguard lightweight compared to the original alloy CAR15 handguards it visually references, while the integral heat shield adds a layer of protection those vintage originals never had, making this a practical upgrade for anyone restoring or building a retro-pattern rifle.

B5 Systems designs every component around function over flash, testing each part thoroughly so builders can trust it on a rifle they depend on.
