[Source] The Karpaki Fifty was a slugthrower sniper rifle. Several modified Karpaki Fifties were used by the Galactic Alliance Guard in 40 ABY. One was used by Ben Skywalker to assassinate Dur Gejjen. Complete with a folding stock, it was small enough that it could just barely be hidden under a jacket when folded. It had moderate recoil, and was equipped with smart sensor optics that automatically adjusted the rifle's scope depending on windage, distance, and the movement of a target.
