I was looking for a way to reduce the overall weight of my AR-308 build while maintaining a solid platform for mounting optics and accessories. The factory handguard felt clunky and outdated, so I began researching lightweight M-LOK options. Upon unboxing, the Guntec USA handguard immediately impressed me with its slim profile and surprisingly light weight.

Compared to the Troy Industries and Midwest Industries handguards I considered, the Guntec USA offered a compelling balance of features and affordability. The Troy was significantly more expensive, while the Midwest Industries, while high-quality, didn’t offer as slim of a profile. My first impression was a pleasant surprise; the handguard felt solid and well-made, exceeding my initial expectations given its price.
