I purchased this sight earlier this year for my MP5. Went to the range one time and worked great. Just purchased my Aimpoint ML2 and now the TAC1 is for sale. Comes in the box with the instruction papers. It only has one lens cover (rear). The front one broke after about 5 open/close actions. No mount included. Excellent condition. Less than 45 minutes on the batteries.
$74 shipped. USPS money order or paypal (add $2).
