Desert Tech Quattro-15 Multi-Caliber Black AR-15 Stripped Lower

The Desert Tech Quattro-15 lower receiver brings a revolutionary quad-stack magazine system to the AR-15 platform. Designed for multi-caliber use and finished in black, this stripped lower is engineered around Desert Tech's proprietary Quadmag architecture while remaining compatible with standard AR-pattern magazines, giving builders a versatile foundation for a high-capacity AR-15 build.

Included with the lower is one (1) Desert Tech Quad53 magazine - a quad-stack design holding an impressive 53 rounds in a standard AR-15 magazine footprint. Four Quad53 mags deliver a 210-round loadout, drastically reducing magazine changes compared to standard 30-round setups. The lower accepts standard AR-pattern magazines as well, so you can run your existing magazines without modification.

The Quattro-15 lower is engineered specifically for the AR-15 platform. As a serialized stripped lower receiver, it provides the foundation of a custom AR-15 build and is intended to be completed with a matching upper receiver, barrel, lower parts kit, and the builder's choice of furniture and trigger components.

Desert Tech's Quattro-15 platform is purpose-built for shooters who demand maximum round count without sacrificing the familiar AR-15 manual of arms. Add your favorite trigger, grip, and stock, pair it with a complete upper of your choice, and you have a high-capacity AR-15 build unlike anything else on the market.
