Halo 4 Play Arts Kai Weapons
 

Hello all,
I recently bought one of the Play Arts Kai red Spartan Soldier and am looking for some other weapons for it. I know they made a dew other weapons for other Halo 4 figures including a Battle Rifle, Assault Rifle and the one I am most interested in, the Rail-gun. Looked around and ask and haven't been able to find any for sale on their own. Would be interested in any of those 3 (and especially the Rail-gun as mentioned). Price is negotiable. Thank you very much!
