“For the past two years I have been shooting in competition with the M400-DH3 rifle and what you get right out of the box is my set-up.  We took our time to release this gun because I wanted all the elements to be my competition set-up from my trigger to the stock,” added Horner.  “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.”

The M400-DH3 Rifle is a SIG Direct Impingement (SDI) aluminum frame rifle with a Cerakote Elite Titanium finish with the DH3 fully adjustable competition stock and a 2-stage adjustable Timney™ Daniel Horner signature trigger.  This competition platform features a 16” fluted stainless 223 WYLDE barrel for optimal 223REM or 5.56 performance with a three-chamber compensator for recoil mitigation, low-profile 3-gun handguard with M-LOK™ mounts for easy accessory attachment, ambidextrous controls including bolt catch/release, and ships with one 30-round magazine.
