The Daniel Defense TYR M4A1 RIS III pairs a 14.5" Daniel Defense M4A1 carbine with the co-built KTMS 12 12-gauge underbarrel shotgun from TYR 1 Outfitters and Allegheny Gun Works, with only 50 units produced in this configuration. Built on a proven Daniel Defense M4A1 host with a RIS III rail, this dual-caliber setup comes equipped with an AAC 51T Muzzle Device, an AAC Rebar Cutter Muzzle Attachment, and an adjustable B5 SOPMOD stock, delivering both 5.56 NATO and 12GA capability in a single package.

With just 50 units in this configuration, this build is designed for collectors and serious enthusiasts who want a rare, pre-assembled tactical system without needing to source parts and assemble it themselves. Once these 50 units are gone, this configuration will not be available again. As an NFA item, transfer through an SOT/Class 3 dealer is required.
