The LMT-AT ION LT FDE is the Flat Dark Earth version of the longest and highest-performing can in the ION family, rated from .17 through .300 Win Mag (LMT-AT part no. ATIONLT-FDE). It is built around patented alternating baffle geometries and a circuitous flow path that reduce gas at the ejection port and keep cycling consistent. Inconel, stainless steel and titanium alloy keep it at 14.7 ounces with cap and base. The kit includes a 5/8×24 single port muzzle mount, and the can is HUB/Xeno compatible. Choose it when suppression performance is the priority and the rifle is finished in tan.
