Thank you for your insight. However, I asked the question relative to the fact that we have seen two '03s in the shop over the past several months that someone is passing off as A4s. Both had a fairly crude cantilevered scope mount attached by screws to the left side of the receiver and obviously were not original configuration sniper pieces. Seems that there maybe someone in this area (Eastern PA) putting these together with modified mounts and selling them to uneducated purchasers as A4s. Hence my question.
