The "LABUYO". Semi-automatic only, S5-DGIS rifle. Caliber 5.56 NATO 14.5-inch barrel in SS-416R UDMC-made barrel from a Bergara blank, 1:8 rifling twist, totally enshroud in a one piece floating KeyMod rail. Receivers and handguards are all in T6 aircraft aluminum. The bloody red color was achieved through the old fashioned but reliably tested method of anodizing.
