The LMT-AT ION 30K FDE is the Flat Dark Earth version of the shortest multi-caliber can in the ION family, rated from .17 through .300 Win Mag (LMT-AT part no. ATION3S-FDE). It keeps the caliber range of the ION 30 in a shorter package, at 5.75 inches with the cap and base installed. A hybrid body of high-temperature nickel and steel alloys is laser welded for strength, and the flow-through design keeps back pressure down. HUB/Xeno compatibility and a 5/8×24 single port muzzle mount come with it. It suits a shooter who wants a short, flexible can and a tan finish to match the rifle.
