Why Choose DT15?

The DT15 isn’t just another AR — it’s a purpose-tuned rifle system built for professionals who demand reliability, performance, and real-world application. Every DT15 starts with a forged 7075 receiver set for maximum strength and includes ambidextrous controls, our patented V2 rail, and tuned gas ports designed to run suppressed or unsuppressed. From the materials we choose to the way each barrel is optimized, the DT15 is built to shoot smoother, last longer, and perform when it counts.

The DT15 16" LT Upper is purpose-built for hard use and delivers rock-solid reliability without being over-gassed. We spec our 4150 CrMoV barrels with a .075 gas port to provide ideal pressure—whether you're running it suppressed or unsuppressed. No tuning. No nonsense. Just performance.
