Radical Firearms Gen 3 M-LOK Handguard – 15″ (Primary Arms Exclusive)
You need a handguard that’s tough, light, and doesn’t cost a fortune. This is it. The Radical Firearms Gen 3, made exclusively for Primary Arms, is built right here in Texas to handle real work.
We run these on our own shop builds. The 6061-T6 aluminum is machined clean, and the hardcoat anodizing stands up to hard use and the elements. At 15 inches, it’s the perfect length to cover a rifle-length gas system and gives you plenty of real estate for grips, lights, and lasers.
Here’s why this handguard works:
- No Flex, No Play: The 3rd-gen mounting system locks onto a 4140 steel barrel nut. When you’re up against a barricade or loading up on a bipod, this thing stays put. The anti-rotation tabs keep your top rail perfectly aligned with your upper receiver.
- Comfort & Control: The profile is slim in hand—just 1.375” inside diameter—so you get a solid, comfortable grip. The full-length Picatinny top rail is seamless for a clean look and solid optic mounting.
- M-LOK Done Right: The slots are positioned for logical accessory placement. It’s compatible with any M-LOK attachment, so setting up your rifle is straightforward.
- Built in Stafford, TX: Radical Firearms backs all their products with a no-nonsense lifetime warranty. If you own it, they cover it. That means something.
This isn’t a showpiece. It’s a functional, reliable handguard that saves you weight without sacrificing durability. For the price, you’re getting a lot of value: American-made materials, a proven design, and a warranty that doesn’t quit.
If you’re putting together a serious, do-it-all AR-15 and want a handguard that just works, grab this one. It’s in stock and ready to ship.
