The DS-15 Typhoon Fixed Magazine Assembled Lower is a complete fixed magazine AR-15 lower built around Dark Storm Industries' patented billet receiver design. Machined from 7075-T6 aluminum, manufactured without a magazine release, and equipped with a permanently affixed 10-round magazine, it provides a premium foundation for fixed magazine DS-15 builds.

The Typhoon lower features partial ambidextrous controls, including a DSI billet 90-degree ambidextrous safety selector, along with a premium single-stage trigger, extended takedown and pivot pins, and the DSI Mil+ carbine buffer system.

Current production models ship with a Magpul DT stock and Magpul K2 pistol grip.
