Fostech “Quadzilla” – Compact Power. Ultimate Control.

Meet The Quadzilla—a purpose-built Fostech configuration designed for shooters who demand premium performance in a compact platform. This build centers around our battle-proven 10.5″ FLITE Eagle AR Pistol, available in 5.56 NATO or .300 Blackout, giving you the flexibility to match your mission, environment, or ammo preference.

At the heart of Quadzilla is the ultralight, rugged Mach 4 Quad Rail Handguard. With quad rail real estate on all sides, you get endless mounting options for lights, grips, and accessories—while maintaining the signature Fostech balance and maneuverability you expect from a top-tier AR pistol.

To push performance even farther, The Quadzilla comes fully outfitted with:

JK Armament 155 G.O.A.T Suppressor

Designed for durability, modularity, and sound suppression efficiency, the 155 G.O.A.T tames muzzle blast and keeps your shooting smooth, controlled, and comfortable—whether you’re training at the range or protecting what matters most.

Vortex Crossfire Red Dot Optic

Fast target acquisition meets rock-solid reliability. The Crossfire’s crisp 2 MOA dot gives you instant visual clarity, allowing you to stay on target even in high-tempo shooting scenarios.
