The Midwest Industries SIG 516 extended free float M-LOK handguard is a precision upgrade that transforms your rifle's ergonomics and modularity. Built for shooters and hunters who want more real estate for optics, lights, and tactical gear, this handguard extends past the factory front sight tower to give you additional mounting space without adding bulk. The free float design isolates the barrel from the handguard, allowing for more consistent accuracy by eliminating harmonic interference—a significant advantage whether you're dialing in long-range shots or running drills at the range.

Constructed from 6061 aluminum and hard coat anodized for durability, this handguard weighs just 8.3 ounces but delivers a rock-solid lockup on your SIG 516. It installs directly onto the factory barrel nut (not included), making the swap straightforward for anyone comfortable with basic rifle work. The monolithic top rail runs 7.25 inches and features five anti-rotation QD sockets, so your push-button swivels stay put under recoil. The M-LOK slots along the forend give you flexible, low-profile attachment points for whatever accessories match your mission—whether that's a bipod for precision work, a flashlight for home defense, or a sling for hunting.

One of the smartest features here is compatibility: this handguard works seamlessly with both bayonet lug and non-bayonet lug SIG 516 models, so you're not locked into a specific variant. The included five-slot M-LOK rail piece adds even more configuration options. Every unit is 100% American-made, a hallmark of Midwest Industries' commitment to quality and domestic manufacturing. If you're running a SIG 516 and want a lightweight, modular upgrade that doesn't compromise barrel harmonics or reliability, this is a no-compromise choice.
