I met up with Josh Whi of Lithgow Arms. They just got ATF approval and the big question last October, at Big 3 East, was “what part will be the firearm?” ATF has approved the barrel housing to be the registered part.
At SHOT 2017 they showed off a CQB model with a 360mm (14.17″) bbl.
On top of the ATRAX F90 is a Trijicon MRO Patrol. It was made to accept covers and kill flash by Tenebraex.
Lithgow USA expects 200 guns in about three months. Stay tuned for more.
