The Reptilia Handguard 10.5" M-LOK in FDE is a purpose-built free-float rail system designed for AR-15 builders and shooters who demand precision and durability. Built from billet 7075-T6 aluminum and finished with mil-spec hard anodize, this handguard delivers the rigidity needed for consistent zero retention and reliable performance whether you're running a precision rifle, duty gun, or competitive build. The 10.5-inch length pairs well with short-barrel uppers and carbines, giving you plenty of rail real estate for mounting lights, lasers, and accessories without adding unnecessary weight.

Reptilia's proprietary turn buckle technology simplifies installation and ensures a rock-solid fit on standard M4 upper receivers. The M-LOK slot pattern has become the modern standard for lightweight modularity—you get genuine MLOK compatibility, so your existing m-slot accessories integrate seamlessly. Every handguard ships with the barrel nut and all necessary hardware, so you're not hunting for fasteners or making guesses about fit.

Made in the USA from billet aluminum stock, this rail won't flex or rattle under recoil or hard use. The FDE color matches today's most popular furniture and tactical aesthetics. Whether you're upgrading a patrol rifle, building a precision trainer, or assembling a compact duty gun, the Reptilia M-LOK handguard is a no-nonsense choice from a maker known for attention to detail.

Frequently Asked Questions

Will this handguard fit my AR-15 upper receiver?

Yes—the Reptilia 10.5" M-LOK is designed to work with all standard M4 upper receivers. It comes with the barrel nut and hardware needed for installation.

What's the difference between M-LOK and other slot patterns?

M-LOK is a popular, modular mounting standard that lets you attach accessories (lights, lasers, rail panels) using standard M-LOK mounts. It's lightweight and offers flexibility to configure your rail exactly how you want it.

Is this a free-float design?

Yes. The handguard is a free-float system, meaning it doesn't contact your barrel, which supports consistent accuracy and zero retention.

Does the barrel nut come installed?

The barrel nut and all required hardware are included, but installation will require proper tools and knowledge of AR-15 assembly. If you're not experienced, have a gunsmith handle installation to ensure proper torque and fit.
