The B5 Systems AR-15 Mid-Length Handguard M-Lok in black is a lightweight drop-in replacement for your rifle's standard handguard. Built with durable composite construction and a stamped aluminum heat shield, this mid-length handguard strips away unnecessary bulk while adding real utility. If you're building a carbine that needs to shed weight without sacrificing ergonomics or modularity, this is a smart upgrade from the factory clamshell design.
What sets this handguard apart is the balance of form and function. Six sides of M-LOK attachment points give you the flexibility to mount lights, ladders, grips, and other accessories exactly where you want them. The slim diameter and built-in handstop mean more comfortable shooting geometry and better handling, especially during extended range sessions or hunting pursuits. The handguard fits both round and triangle-shaped handguard caps, so you're not locked into one aesthetic.
At 5 ounces and 9 inches long, the mid-length version sits right in the sweet spot for balancing sight radius with maneuverability. The composite material keeps things light and affordable, while the integrated heat shield protects your hand and any attached accessories from barrel heat. This is the kind of no-nonsense upgrade that improves your AR-15's handling without the complexity or cost of a full rebuild.
