Overview
The Fortis Low Profile Gas Block - Mod 2 is designed to fit a .750 diameter gas port, making it ideal for builders looking to enhance their AR-15's gas system. This clamp-on gas block features a low-profile design, which allows for seamless installation under handguards while ensuring durability thanks to its steel construction and nitride finish. It’s commonly found in extended rifle builds chambered in .223 Wylde, where reliable gas flow is crucial for optimal performance.
