I have a lightly used Aimpoint Acro P1 (takes CR1225 batteries). The dot size is 3.5 MOA. It will come with 8 spare batteries and a carboard box from Aimpoint. I live in Auburn and will need you to come to me. I'm not interested in trades, but feel free to comment on whatever you're looking to offer and if I'm interested I'll PM you. Price is firm. If you have questions about the specific unit feel free to ask. If you have questions about the technical specs then google is your friend.
