Sig Sauer - M400 DH3 223 Wylde 16" Rifle - RM400-SDI-16B-DH3
Sig SauerAfter two years of competitive testing with SIG SAUER’s SDI Comp Rifle, Team SIG’s Daniel Horner has fine-tuned the platform to create his ideal competition setup—the M400-DH3 from SIG Custom Works. This marks the first rifle to come out of the SIG Custom Works line and is purpose-built for 3-Gun competition. It features fully ambidextrous controls, including a new SIG-designed ambi bolt catch and release, a Timney DH3 Two-Stage Trigger, a custom DH3 Adjustable Stock, and a fluted stainless 223 Wylde barrel for top-tier performance with both 5.56 NATO and .223 Rem. A 3-chamber compensator significantly reduces muzzle rise, keeping you on target shot after shot. Built for champions, the M400-DH3 is the exact rifle used by 10-time 3-Gun champion Daniel Horner—and now it’s available to you.
