I have a new ACOG TA31RCO-M4CP that I picked up for use on my rifle but have recently found out is not authorized for use. I have put the LaRue RCO mount on it and mounted it to the rifle but it has never been fired. Includes the original box, all manuals, registration card, lens brush, coyote MOLLE carrying case, scopecoat cover, original mount, killflash, and everything else that came with the optic. Asking $1100OBO shipped to the lower 48. I would also take an Aimpoint CompM4s or PRO as partial trade. Thanks!
