Muahaha got mine just now. First impressions...VERY high quality build. The reticule is great but is a bit hard to see when aiming it at a bright tree outside. No problems indoor though.
Its also slightly tilted towards the left when fitted to my CA m15a4...
Edit:Oh yeah I found some really cool thing about the reticule. At any distance looking at the reticule, it stays the same size, so even when your eye is right up to the sight, or when you are looking further away, the reticule stays the same. Really cool.
