Whether you’re interested in the ultimate 3-Gun rifle or simply want an AR-platform rifle capable of stellar performance, the Sig Sauer M400 DH3 is well worth a closer look.

Sig Sauer released the following details about the M400 DH3:

Team SIG’s Daniel Horner has refined the platform to meet his competition needs and developed the ultimate 3-Gun rifle, the…M400-DH3 from SIG Custom Works. The first-ever rifle from SIG Custom Works features full-ambi controls with the new SIG-designed ambi bolt-catch and bolt-release, a Timney DH3 Two-Stage Trigger, a custom DH3 Adjustable stock, fluted stainless 223 Wylde barrel (for optimal 5.56 and 223 Rem performance) and a 3 Chamber Compensator for muzzle rise reduction. The new M400-DH3 from SIG Custom Works gives you the same competitive edge and the same rifle used by 10-time 3 gun champion Daniel Horner.

Although it is listed as being chambered in 5.56 NATO, it does have a 223 Wylde barrel, meaning the shooter will get superior accuracy whether running 5.56 NATO or 223 Remington. The handguard has a Picatinny rail over the receiver and at the muzzle end and is M-LOK compatible, so shooters can add whatever accessories are needed for competition or range use. It has a 2-stage trigger made by Timney Triggers which is, in fact, the company’s Daniel Horner Signature Trigger, and ambidextrous controls. Each rifle ships with a 30-round magazine.

Perhaps the most eye-catching feature of the Sig Sauer M400 DH3 is the stock, which was designed by Daniel Horner. It’s adjustable for length of pull and has a unique aesthetic that is attention-getting, to say the least. The streamlined design also serves to reduce overall weight and create a more balanced rifle.
