I have a nice used Leupold Vari-X III 3.5-10X40 for sale in DFW. It is in great shape with very minor ring marks and perfect glass. It has been used on a heavy .308 so has not been beat up with heavy recoil. Will come with BC flip covers. Sell for $400 or trade for a SS 10X plus cash.
I also have a nice used Eotech 512 for sale. It is in good used shape with a few scratches but good glass. It has a front GG&G cover. This model uses AA batteries. Sell for $300. SOLD
