The other day I went to purchase a Bushnell 3200 Elite. I looked at about a half dozen of the same model and noticed they appeared of different construction. Some were what appeared to be of one piece construction with their turrets, while others appeared to have turrets glued (for lack of the proper term) to the tube. I am puzzeled by this and wonder why and if it makes any difference. Can anyone help me with this question? spit
