Selling used Aimpoint Comp M4 $450 FIRM. It is a military surplus and is beat up a bit but works fine. I am located in Lubbock, I am willing to ship or do local pickups. If shipping I would want a USPS money order and would ship once it cleared my account. I would charge $10 for shipping to the lower 48. Thanks guys!
