Designed in partnership with world champion 3-Gun competitor Daniel Horner, New Hampshire-based Sig Sauer this week announced the new DH3 competition platform in its M400 rifle series.

The M400 DH3 rifle is a Sig Direct Impingement aluminum frame rifle with a Cerakote Elite Titanium finish and DH3 fully-adjustable competition stock. Standard from the factory is a two-stage adjustable Timney Daniel Horner signature trigger and a 1:8-twist 16-inch fluted stainless .223 Wylde-chambered barrel with a three-chamber compensator for recoil mitigation. Other features include a low-profile 3-gun handguard with M-LOK slots, and ambi controls, including bolt catch/release, charging handle, and selector switch. 

Horner, considered one of top multi-gun and 3-gun shooters in the world with over 125 championship titles at the world, national, regional, and state level to his name, has been wearing Team SIG's colors for the past couple of years, and it is in this collaboration that the M400 DH3 was developed. 

"Since Daniel Horner joined Team SIG, he has methodically been researching, designing, and testing the products he will be introducing through the DH3 brand from Sig Sauer," said Tom Taylor, CMO and executive VP of commercial sales for Sig. "These are not just products that bear his name, but are the products that have been tried, tested, and used by him personally. Daniel puts the full force of his name and his distinguished career in the shooting sports behind this new rifle."

"I’ve won multiple titles with this exact build and even if you’re not taking it into competition, you are sure to enjoy the custom features that we have put into the M400-DH3," noted Horner, who has 16 Multi-Gun/3-Gun Championships, eight Sniper Championships, two IDPA National Championships, an IPSC Shotgun National Championship, and an NRA World Shooting Championship among the national and major title wins throughout his career.
