There are lots of sales going on right now to liquidate the Kahles Helia CL series of scopes that are being dicontinued. Prices are very low and was wondering if these would be worth buying? Models are 2-7x36 51701 $499 New, 3-9x42 51711 $599 New/w side parallex adjustment. These prices seem too good to be true. Are these scopes made in Austria? Thanks
