Its main attraction is the ability to chamber and fire devastating <b>A19 'hard-slug' tungsten rounds,</b> infamous for their overpenetration abilities. The thicker barrel, of course, also has no issue with non-HV ammo."
+	desc_lore = "The USMC was not terribly enthusiastic about unproven hand-held plasma weaponry. Before the XM99A was eventually adopted into use, the USMC instead sought out a traditional squad-portable, precision, armor-piercing weapon, and contracted ARMAT to upgrade their M4RA platform to be capable of firing advanced AP rounds. They succeeded- sort of. The R2 is a killer, but also a piece of junk. It kicks hard enough that precision sights simply don't stay zeroed, its oversized muzzle-barrel extends an already long barrel-length, and A19 ammo, already expensive, was driven to absurd highs by the specification of depleted uranium slugs."
