Strike Industries GRIDLOK® 416 Lightspeed 9" – Quick Detach M-LOK® Handguard for HK416 / MR556 / M27 IAR (Black) Fast removal, rock-solid return, compact control. The Strike Industries GRIDLOK-416-L-9 is a 9-inch, 1.57" OD free-float handguard engineered specifically for HK 416, HK MR556, and M27 IAR platforms. With the signature GRIDLOK® Quick Detach system, you can pull the rail without tools to access your piston/gas system, then reinstall with a secure, repeatable lock-up—so your lights, lasers, and irons stay right where you zeroed them. Machined from lightweight black anodized aluminum and packed with M-LOK® mounting slots, the 9" Lightspeed length is ideal for SBRs, suppressed setups, and close-quarters carbines that need serviceability and stability in equal measure. Model/MPN: GRIDLOK416L9 • UPC: 793811764673 Why the GRIDLOK 416 Lightspeed 9" stands out Rapid QD access: Strike’s GRIDLOK® Quick Detach latch gives tool-less removal/reinstall in seconds for piston cleaning, gas tuning, or muzzle device changes—no more fighting barrel nuts or losing time between stages. Return-to-zero confidence: Reinforced anti-shift geometry and a rigid interface help maintain zero retention for aiming lasers, IR devices, and front sights after QD cycles. Compact 9" control surface: Perfect for short barrels and suppressor-forward builds—keep switches close, manage cables cleanly, and maintain a balanced center of gravity. Slim 1.57" diameter: Comfortable, glove-friendly circumference supports modern C-clamp grips without hot spots. M-LOK® everywhere you need it: Clean slots at 3, 6, and 9 o’clock for handstops, QD sling cups, lights, bipods, and cable guides—no extra rail sections required. 416-correct fitment: Built for HK 416 / MR556 / M27 IAR architecture for proper clearance around the piston assembly and 416-spec interface parts. Key features at a glance Platform compatibility: HK 416, HK MR556, M27 IAR Length: 9 inches (Lightspeed) Outside diameter: 1.57 inches (low-profile, ergonomic) Attachment: GRIDLOK® Quick Detach (tool-less removal/reinstall) Mounting system: M-LOK® accessory slots Construction: Lightweight, precision-machined aluminum Finish: Black (durable anodized) Profile: Free-float to promote accuracy and consistent barrel harmonics Model / MPN: GRIDLOK416L9 UPC: 793811764673 Built for performance—and serviceability The GRIDLOK 416 Lightspeed 9" keeps your carbine mission-ready and easy to maintain. The free-float architecture removes external pressure from the barrel, supporting accuracy, while the QD mechanism gets you to the piston and gas block instantly for carbon cleanup or diagnostics. Extended M-LOK real estate provides modularity for today’s pressure pads and cable routing—especially critical when you’re running a can or working in tight interiors. Ideal use cases SBRs / PDWs / CQB: Short, maneuverable rails that keep support-hand placement close and control crisp. Suppressed carbines: Better cable management and pad placement around cans and brakes. Duty & professional setups: Repeatable alignment for lasers/illumination with rapid maintenance access. Competition & training: Stage-side serviceability without sacrificing rigidity or zero. Compatibility & fitment notes Designed for HK 416 / MR556 / M27 IAR platforms using the 416-specific interface. Not for standard AR-15 barrel nuts or DI-only setups—confirm your platform before purchase. Verify barrel profile, gas piston clearance, and muzzle device length, especially on pinned/welded systems or oversized suppressor mounts. If your upper has unique tolerances or aftermarket components, check fit and alignment before hard use. Installation tips Professional installation recommended. Follow Strike Industries torque specs and thread-prep guidance. After mounting, hand-cycle to confirm unobstructed piston travel and accessory clearance. Reconfirm zero on all aiming devices after initial install and after any QD removal/reinstall. What you’ll notice on the gun Solid lock-up that feels like a bolted-on rail—without giving up QD convenience. Cleaner cable routing thanks to plentiful M-LOK slots and low-profile geometry. Neutral balance on short barrels and suppressed builds, improving transitions and target-to-target speed.
