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.

SAME GREAT UPPER – DOES NOT INCLUDE BCG OR CHARGING HANDLE.

CRANE SPEC DT15 is purpose-built for duty use with a dedicated suppressor. We designed this upper to run defensive and duty ammo without the excessive gas common in commercial rifles. No need for adjustable gas blocks, special buffer weights, or tuned springs. It cycles reliably suppressed—whether you're shooting training ammo or full-power 5.56—thanks to a .070 gas port and our 9.6" M-LOK rail system.

DUTY SPEC DT15 is tuned for hard use with full-power defensive ammo—suppressed or unsuppressed—without over-gassing. With a .071 gas port, this setup eliminates the need for special settings or adjustable systems. It will cycle some .223 ammo, but is optimized for NATO-spec pressure loads. Comes paired with our 9.6" M-LOK rail system.

COM SPEC DT15 is built to eat anything you feed it. Designed around a .073 gas port, it accommodates a wide variety of 5.56 and .223 ammo. If you need one upper to do it all—suppressed, unsuppressed, training, defense—this is the one. Equipped with our 9.6" M-LOK rail system.

DC SPEC DT15 bridges the gap between DUTY and COM, offering enhanced reliability across both .223 and NATO-pressure 5.56. Available in multiple barrel lengths and paired with length-matched MRS V2 rails:
