The Daniel Defense TYR M4A1 RIS III kit is a complete build that puts a 5.56 rifle and a 12GA underbarrel shotgun into one ready-to-run package. Built around the Daniel Defense M4A1 host with a 14.5" Daniel Defense barrel and RIS III rail system, this kit pairs a KTMS 12 underbarrel shotgun with an AAC 51T Muzzle Device and an AAC Rebar Cutter Muzzle Attachment, alongside a full EOTech optics suite, an OGL green and infrared aiming laser, and a SureFire dual-fuel Scout Light.

You don't have to track down a dozen premium parts, wait on backorders, or piece the build together yourself. The EOTech EXPS3 and G33 magnifier on a Unity Tactical FAST FTC OMNI mount let you move seamlessly between fast close-range engagement and 3X magnification. The Unity ModButton Lite SYNC puts both light and laser control under one thumb. For collectors and serious enthusiasts, it is a complete, high-capability tactical package ready in a single step.
