The beast of Third Dot Arms. This is the 20mm AMR-371, the most advanced Anti-material Rifle in the market today. In its brief use by PMC's and military's across the world the AMR-371 has bagged 2 world records including the longest confirmed sniper kill, and the longest shot with a man portable 20mm weapon. Third Dot plans on gunning for the worlds longest rifle shot in history with this weapon as well once they unveil their long awaited "Alpha-Bravo" pack for the AMR-371.
The AMR-371 fires a number of rounds, including custom 20mm "Long" rounds which offer 30mm power in a 20mm shell. For a size comparison, a 50 cal. BMG has been placed by a 20mm Long Round.
(Make sure to watch out for the "Alpha-Bravo" pack in the coming week.)
