Sam Fisher- SIG 516

  Leaving nothing to chance, they’d donned their tac-suits and goggles and had brought along both their primary and secondary pistols as well as SIG516 rifles slung over their backs. The rifles had 10.5 inch barrels and were fitted with thirty round magazines of 5.56mm ammo. Better yet, those rounds were factory fresh, not reloaded by Russians whose fingers were covered in peanut butter. The rifles were also fitted with grenade launchers, but said grenades had been replaced by the less-than-lethal sticky shockers like the ones Fisher had used with his crossbow.
