The Tyr 1 Outfitters M4A1 RIS III Kit is a complete, house-assembled build that puts a 5.56 rifle and a 12GA underbarrel shotgun in one ready-to-run package. Built around the M4A1 RIS III host with a 14.5" Daniel Defense barrel, this kit pairs a KTMS 12 underbarrel shotgun with a full EOTech optics suite, an OGL green and infrared aiming laser and a SureFire dual-fuel Scout Light, all set up together by Tyr 1 Outfitters.

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 between fast close-range work and 3X magnification. The Unity ModButton Lite SYNC puts light and laser control under one thumb. For collectors and serious enthusiasts, it's a complete build you can buy in one step instead of spending months assembling it.
