B5 Mlok Hndgrd Carb Lngth

The B5 Systems M-Lok Handguard in carbine length is a free-floating modular rail system designed for AR-platform rifles requiring a lightweight, low-profile foregrip solution. Built around the M-Lok attachment standard, this handguard delivers a streamlined profile while maintaining full compatibility with the growing ecosystem of M-Lok accessories available to today's rifle builders and operators.

The carbine-length configuration spans approximately 7 to 9 inches, making it ideal for short-barreled rifles, pistol-caliber carbines, and compact defensive builds where barrel length is constrained by legal or practical limits. The M-Lok slots are precision-machined to accept industry-standard M-Lok fasteners, allowing shooters to attach vertical grips, barricade supports, sling mounts, and tactical accessories without rail clutter. The free-floating design minimizes contact with the barrel, reducing harmonics that can affect shot grouping during precision fire.

This handguard suits AR-15 builds targeting home defense, law enforcement patrol rifles, competition shooting, and general-purpose rifles where weight savings and modularity matter. Shooters who prioritize bare-bones aesthetics and the flexibility to add only the accessories they need—rather than pre-installed Picatinny rail—find the M-Lok standard reduces unnecessary weight and complexity. The carbine length is particularly popular for SBR builds where keeping overall system length compact is essential.

B5 Systems has established itself as a precision handguard manufacturer focused on clean geometry and proven reliability across military, law enforcement, and civilian platforms. The M-Lok standard, developed by Magpul, has become the de facto modular accessory interface for modern rifle systems, offering proven durability and broad aftermarket support.
