The Drivelock™ handguard, developed in collaboration with Icon Defense, brings a breakthrough, patent-pending locking system to AR-style rifles. Its innovative Drivelock design uses three independent wedges that engage angular grooves in the supplied proprietary barrel nut, clamping the rail to the barrel nut with surgical precision and massive holding force. That same action also pulls the handguard rearward toward the upper receiver for an ultra-tight interface that reduces movement under recoil and improves accuracy potential.
Built from lightweight aircraft-grade aluminum and finished in durable hard anodized black, the extrusion’s slightly larger inner diameter provides extra real estate around the gas block and increases rigidity compared to similar designs like the M76. The larger ID also helps the handguard run cooler during extended shooting sessions. The Drivelock system ships complete with barrel nut, barrel wrench, and lock-up components for a straightforward installation.
Available lengths: 16.75″, 15″, and 13″ — choose the size that fits your build and mission. Shop all lengths now at AR-15 Discounts for competitive pricing, fast shipping, and the accessories you need to finish the job.
