The Guntec Air-Lok Handguard (brand part no. GT-5ALC) is a short, 5-inch M-LOK handguard built in a lightweight modular design with triangle cuts running through the body to shave weight. Instead of the six-screw lockup used on Guntec’s longer Ultra Light handguards, the Air-Lok slides over its barrel nut and compresses down with four screws, giving the monolithic top rail a tight fit against the receiver on a compact pistol or SBR-length build.
