Machining and quality is about as good as you are gonna see in a pin sight. In fact the machining is like a whole other level vs. most other makes..........I have the " Hogg-It" for 3D and have been so thoroughly impressed with it that am seriosuly considering the " Hogg-It Hunter" for my hunting bow.........I think you could pound nails with one and it would look as good as the day you bought it. It' s some serious coin for a pin sight but the quality and Lifetime warranty makes it probably the last pin sight I' ll ever need.
