The TYR 1 Outfitters M4A1 RIS II pairs a 14.5" Daniel Defense M4A1 carbine with the TYR 1 Outfitters and Allegheny Gun Works KTMS 12 underbarrel shotgun, and only 50 will ever be built. The Daniel Defense M4A1 carbine wears the RIS II rail and comes with an AAC 51T muzzle device, an AAC Rebar Cutter muzzle attachment and a B5 SOPMOD stock, giving you 5.56 and 12GA in one package.

With just 50 units in this configuration, this is a build for collectors and serious enthusiasts who want something few other shooters will own. The Daniel Defense host and the co-built KTMS 12 underbarrel shotgun come together as one package, so you don't have to source the parts and assemble it yourself. Once these 50 are gone, this configuration won't be available again.
