Sig Sauer M400 DH3 .223 Wylde

The Sig Sauer M400 DH3 is a premium competition-ready AR-platform rifle designed in collaboration with 3-Gun champion Daniel Horner. Chambered in .223 Wylde, this rifle offers the versatility to safely and accurately fire both .223 Remington and 5.56 NATO, giving shooters the best of both worlds in terms of performance and ammunition flexibility. With a 16-inch stainless steel barrel and precision-engineered components, the M400 DH3 is built for speed, accuracy, and reliability in high-performance environments.

The rifle features a free-floating M-LOK handguard for enhanced modularity and weight reduction, along with an adjustable two-stage match trigger that delivers a crisp, consistent break ideal for competitive shooting. Its custom DH3 adjustable stock allows for fine-tuned length of pull and cheek weld to match individual shooter preferences, while the flat-faced trigger and enlarged controls support rapid manipulation during fast-paced stages.
