MODEL: RM400-SDI-16B-DH3 | CALIBER: .223 / 5.56x45MM

After two full years of competitive shooting with SIG SAUER'S SDI Comp Rifle, Team SIG's Daniel Horner has refined the platform to meet his competition needs and developed the ultimate 3-Gun rifle, the new 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.
