The ProMag Industries AR-15 Carbine Polymer Quad Rail Hand Guard is a lightweight, modular mounting platform designed for shooters who demand accessory flexibility without compromising ergonomics. Built for tactical, competitive, and recreational rifle builds, this quad rail handguard provides immediate picatinny real estate for optics, lights, lasers, and vertical grips.
Constructed from reinforced polymer, this handguard delivers rigidity comparable to aluminum rails while weighing approximately 0.59 lbs—a critical advantage in prolonged shooting sessions or duty carry applications. The four-rail configuration provides 360-degree modularity, allowing you to position lights, PEQ units, or backup iron sights exactly where your shooting platform demands them.
This handguard is engineered specifically for direct-impingement AR-15 carbines, fitting standard 0.75-inch diameter gas tubes. Its polymer construction resists corrosion and temperature cycling better than bare aluminum, making it ideal for field operations in harsh environments. The rails are machined to standard picatinny dimensions, ensuring compatibility with all MIL-STD-1913 accessories.
