Armalite's IP rights over the AR-10 & AR-15 has long expired. The B&T SMG was introduced in the early 2010s. Shouldn't they have IP rights over the design for another decade or so ?No arrangements they will hold the IP themselves not hard to get just like how they hold IP for their AR
Oh..I see.9mm they say it fires fine with imported ammo but has trouble with Indian OFB 9mm(could be ammo quality issue) and they are working towards solving it hence didn't take part in trails
