The LMT-AT ION 30 in Armorer Black is the flagship of the LMT Advanced Technologies ION suppressor line, a multi-caliber rifle can rated from .17 through .300 Win Mag (LMT-AT part no. ATION3). It sits between the compact ION K and the performance-first ION LT, balancing performance, size, usability and serviceability. A flow-through design reduces back pressure for both the shooter and the rifle, using patented alternating baffle geometries and an obstruction-free blast chamber. The removable base and cap make it user-serviceable. It is the ION to pick when one suppressor has to cover several rifles and calibers.
