There is a new company that is being introduced in the Innovations Zone called Clear Targets at booth #31. The lenses they have are great! I am currently shooting one in my Axcel Armortech HD and Axcel Achieve with their AX-41 scope. I love having a lens and don't think that I will ever not use one as long as local hunting laws permit. The sights were awesome before with their micro adjusting and super tough design, but with the Doc's Choice Lens by Clear Targets it is even better! Check them and TRU Ball/Axcel Sights out at the ATA Show in a few days at booth #1053 also. A pair of these two products is a deadly combination for game and targets! Good shooting!
