B5 Systems Drop In AR-15 Handguard - M-LOK - Carbine Length

The B5 Systems Carbine Length M-LOK Handguard is a drop-in replacement for the standard clam-shell handguard found on most carbine-length AR-15s, adding M-LOK accessory mounting without a free float conversion. This two-piece composite handguard measures 7 inches long and installs using the rifle's existing delta ring.

• Two-piece drop-in design
• Durable composite construction
• Built-in aluminum heat shield
• Slim diameter with built-in handstop
• Six sides of M-LOK attachment
• Fits round and triangle handguard caps
• 1.75" width, 3.90 oz weight
• Coyote Brown finish

Because it's a direct drop-in for the factory clam-shell handguard, this upgrade doesn't require a new barrel nut or gas system work, making it one of the fastest ways to add M-LOK mounting to a stock-profile carbine. The built-in handstop and slim diameter improve grip and control over the original round handguard, and the integrated aluminum heat shield keeps handguard temperatures manageable during extended shooting. Since it fits both round and triangle handguard caps, it works across most common carbine-length delta ring setups without needing to identify your specific cap style ahead of time, and at 3.90 ounces it adds negligible weight over the factory clam-shell it replaces.

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