Expo Arms 15″ M-LOK AR-15 Handguard – Black
Price: $75.90
You need a handguard that works. This one does. We’ve run these on our own rifles and trust them. It’s a straightforward, no-nonsense free-float tube that gives you a solid platform for your light, grip, or laser, without the bulk or the outrageous price tag.
What You Get
This is a 15-inch handguard. That means it’s the perfect length for a 16-inch barrel rifle, giving you plenty of real estate to grip out front and mount your gear. It’s machined from a solid block of 6061-T6 aluminum, not cheap cast metal. The black hardcoat anodizing is durable; it resists wear and chemicals.
The design is slim. Your hand fits around it naturally, and the inner diameter is a full 1.35 inches, so it clears low-profile gas blocks without a fuss. It locks up tight with anti-rotation tabs and a matching 6061 aluminum barrel nut. Once it’s torqued down, it’s not moving. It’s compatible with any standard Mil-Spec upper receiver.
Built for Attachment
M-LOK is the standard for a reason. This handguard has M-LOK slots on all seven sides—3, 6, and 9 o’clock, plus the 1:30, 4:30, 7:30, and 10:30 positions. Attach anything, in any configuration, directly to the rail. No bulky adapters needed. It keeps your setup clean and lightweight, coming in at 18.2 ounces.
Whether this is for a fresh build or replacing a clunky old quad-rail, this handguard gets the job done. It’s a functional upgrade that improves handling and utility.
