Aero Precision M5 Atlas R-One M-LOK Handguard 15″ FDE

Upper receiver builds require thoughtful handguard selection, whether you're working on a rifle in Livermore or anywhere across California. The 15-inch M-LOK design offers genuine modularity for optics and accessories. Before assembling or transferring firearms, understand your obligations under California firearm laws, which govern both retail purchases and component assembly.

M-LOK slot spacing and rail geometry

This 15-inch handguard delivers consistent M-LOK spacing across its full length, letting you position tactical components exactly where you need them. The design balances weight with structural rigidity for sustained accuracy work. If you're sourcing parts through a private party transfer process, ensure all components comply with your local assembly guidelines. FDE finish matches most modern rifle builds and resists fingerprints during handling. TacticCAL is your local gun store in the Bay Area.
