Radical Firearms Gen 3 M-LOK Handguard – 15″ (Primary Arms Exclusive)

$131.99

This isn’t just another handguard. This is the Radical Firearms Gen 3, made exclusively for Primary Arms. We’ve run these on our own builds and trust them. It’s built for shooters who want a no-nonsense, lightweight rail that doesn’t cut corners on strength.

Machined right here in Stafford, Texas from a solid block of 6061-T6 aluminum, it’s tough. The hardcoat anodizing is what you want—it resists wear and handles the elements. The profile is slim and comfortable in the hand, which matters on a long day at the range or in the field. It keeps weight down without feeling flimsy.

The top is a full-length Picatinny rail, perfectly straight and seamless for your optic. It locks onto any MIL-SPEC upper with anti-rotation tabs, so your zero stays put. The heart of the system is the Gen 3 mounting hardware. It uses a heavy-duty 4140 steel barrel nut and a clamp-style design that gets everything tight. We’re talking solid—minimal flex when you’re up against a barricade or using a bipod.

With a 15-inch length, it covers a rifle-length gas system easily, giving you plenty of real estate for your grip, light, or laser. The M-LOK slots are where you need them, so attaching your favorite accessories is simple and secure.

Radical Firearms stands behind this with their lifetime warranty. If you own it, they cover it. That’s confidence you don’t get from every brand.

Bottom Line: For the price, you’re getting a proven, American-made handguard that does the job right. It’s a core component for a reliable rifle build.
