Accurate enough and when loaded with AP has the reach to put rounds through lightly armored portions of BMPs (gunports, observation slits, rear armor on early BMP models, etc). Penetrates a brick wall almost 2ft thick, too (sending deadly chunks of brick flying in all directions).
B-Light is fukin awesome against......well, people.......up to 6,000 ft accuracy!!!!
OMG, i find it funny how we both know about that world gun's page, lol.
But yeah, that's freakin' lethal.
