I have several of the Tasco scopes. I have 2 World Class Plus 6x42, Japanese made. They are good value. I also have thee of the older Titans, made in Japan. Two are 1&1/2 x6x42 and the third is 3x9x42. All three are superb. They have one piece aircraft aluminum tube, all lenses are multi-coated. Disadvantages: the Titans are heavy (16-19oz.)with 30mm tubes and the reticle is on on the first optical plane. Advantages are superb optics-certainly better than my Leupold Vari x IIs, fast focus, accurate click adjustments and rock solid reliability. These titans were suposed to compete with the high dollar Euro brands. In this, they failed miserably. Think about a $60,000 Subaru.
Having said the above, the Tasco scopes that were produced in Asia
(Non-Japanese) are absolute crap. I speak from expeiriece. The later WC, WCP, and the later TITAN are absolute junk. Stoney
