I have an used Aimpoint Comp M2 for trade. I comes with a special bolt on quick disconnect mount, Killflash filter in the objective, and original box with spare battery. This is a well used red dot, but works flawlessly. I will trade it for an Eotech 557 night vision ready only. Will consider cash if the price is right. Currently mounted on my AA .50 Beowulf AR15. PM me for offers!
