Halo Weapons Part 15-Marksman Rifle

I don't have many details of this weapon but what I know that this weapon function was just like Battle Rifle, this weapon is effective to heavy armored units like Brutes or Elites armors, but the difference between battle rifle and the Battle Rifle is not just the shape and apparent, but the firing, apparently this weapon shot one bullet at a time with no cool down, but Battle Rifle shot three bullet at a time and required a few Time to shoot again

Just like Battle rifle, the weapon can also be zoomed, and contains 32 ammo in one magazine just like battle rifle, the weapon was effective against heavy armored units, but not good at agile and light units, apparently this weapon was a good choice against long ranged enemies
