I have 2 of the Aetec scopes with the True Zero system. Bought them as soon as they came out. One had the Eye Piece come out and I was given a new scope under warrantee. 2.5-10x44 and a 4.5-14x44. Optically they have been great scopes. Hold zero and adjustment is 1/2" per click. Both scopes have Electrical tape on the Eye piece focus adjustment, to lock them in place. The Chinese factory used a soft Plastic Button as a stop in the eye piece adjustment. The scope could have been a winner, But the Meade/Simmons penny pinchers over rode the Designers on the quality control in manufacture. I got a bit of inside info years ago at hunt camp from engineering side people that designed the scope system. What was designed and planned was different than what was sold. Design a BMW construct a Yugo off the plan, type of corporate decisions Process.
