I purchased an Aztec Emerald 5.5X25X50 for my Bantam Sniper because of all the great things people were saying about them, the Aztec is very nice, however the crosshairs are hard to see with certain backgrounds and when you go over 20X the clarity really suffers. Last week I purchased a Bushnell Engage 6-25X50 both scopes are 30mm tube. The Bushnell is superior in every way, build quality, clarity even at full power, crosshairs are dam near perfect, scope is shorter and lighter. The best part is the Bushnell was $50 less. Compared to the Bushnell the Aztec is overpriced. Bushnell also has a superior warranty in terms of service. I can see myself buying another one of these Engage scope. Both scopes focus down to 10 yards.
