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

The B5 Systems Mid-Length M-LOK Handguard is a two-piece drop-in replacement for the standard clam-shell handguard on mid-length gas system AR-15s, adding six-sided M-LOK mounting without a free float conversion. Built with the same slim diameter and handstop as B5's carbine-length handguards, this version is sized for mid-length rifles.

• Two-piece drop-in design
• Durable composite construction
• Built-in stamped aluminum heat shield
• Slim diameter with built-in handstop
• Six sides of M-LOK attachment
• Fits round and triangle handguard caps
• Black finish

Because it drops directly onto the existing delta ring, this handguard upgrades a stock mid-length AR-15 to M-LOK mounting without touching the barrel nut or gas system. The built-in handstop improves grip over the factory clam-shell, and the aluminum heat shield keeps handguard temperatures manageable during extended strings of fire. It carries the same two-piece composite construction and six-sided M-LOK layout as B5's carbine-length handguards, just proportioned for a mid-length gas system rather than a carbine-length one, so confirm your rifle's gas system length before ordering.

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