The Daniel Defense TYR M4A1 RIS II builds on a 5.56 host with a 14.5" Daniel Defense barrel, a 12GA KTMS 12 underbarrel shotgun, an AAC 51T muzzle device with an AAC Rebar Cutter muzzle attachment, and a B5 SOPMOD stock. Sighting is handled by an EOTech EXPS2-0 holographic weapon sight with a 68 MOA ring and 1 MOA dot, carried at a 2.26" optical height on a Unity Tactical FAST riser. A SureFire Scout Light Pro supplies 1000 lumens of white light and a B5 P Grip 23 finishes the controls. This configuration runs the EXPS2-0 on its own with no magnifier, laser, or remote switch, and as an NFA item it transfers through an SOT dealer.
