The LMT AT ION LT is a full size 30 caliber rifle silencer that uses hybrid design in both its signature suppression technology, as well as in its material makeup.  Utilizing both Inconel and titanium alloys, the ION LT provides significant durability in a lighter weight envelope than silencers of similar size.  The backpressure reduction with the ION LT is significant; it reduces the propensity for blowback on semiautomatic weapons and reduces the severity of ejection port blast to the weapon operator, thus increasing operator level of protection, reducing hazard.  The end cap is removable; the 556 flash hiding end cap is highly recommended for use on 556 weapons.  The ION LT is also HUB-mount capable; the included mount system is Xeno muzzle device compatible.

In this review, the LMT AT ION LT performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a commonly fielded gas-operated rifle, which is an incredibly difficult task. How would the LMT AT ION LT perform on your MK18 with a 10.3-in barrel?
