The Guntec Ultra Light 7-Inch M-LOK Handguard in carbine length (brand part no. GT-7MLK) is a free-floating handguard for the AR-15 platform. Guntec USA machines it from a T6 aluminum body and finishes it in anodized black. A proprietary barrel nut is included, and the rail slides over that nut before it locks up against the receiver with six screws. That tight fit leaves a monolithic top rail for steady optic mounting. It is a lightweight way to rebuild an upper with the M-LOK system, and Guntec makes it in the USA.

Key Specifications

• The handguard is 7 inches long in Guntec’s carbine length, which sets how much of the barrel it covers.
• The body is a T6 aluminum in 6061 grade, which keeps the weight down without giving up rigidity.
• The finish is anodized black, a durable black coating.
• Accessories attach through the M-LOK system, so lights, grips and bipods mount without a separate rail section.
• The internal diameter is 1.34 inches, the opening the handguard needs to clear the barrel and gas system.
• The rail has a monolithic top rail thanks to a tight fit against the receiver, so optics and sights sit on one continuous surface.
• A proprietary barrel nut is included, so the handguard installs without sourcing a separate nut.
