The LMT-AT ION 30 FDE is the Flat Dark Earth version of the flagship ION suppressor, a multi-caliber rifle can rated from .17 through .300 Win Mag (LMT-AT part no. ATION3-FDE). LMT-AT says the ION 30 is designed to support the widest range of calibers and use cases in the ION family, with a profile between the compact ION K and the longer ION LT. A flow-through design keeps back pressure down, and the laser-welded baffle stack holds alignment for precision and duty use. The removable base and cap let you service it yourself. It is a natural fit for a tan rifle build that needs one can across several calibers.
