There is one in the game at the moment. The X-55. We need others,because having a gun much longer than the rifle that shoots as far as a small child can throw a rock is just plain silly.
I second that! I love the X-55 and have all my snipers (and HK-51's) equipped with it, because it looks much better than typical sniper rifles. I would love to have other similar small-sized sniper rifles on the Cartel Market!
