I guess dropping it off early is the least the guy could do, considering he checked off the no one home, but didn't actually bother to knock or ring the doorbell.
The rail is fairly low. The sight is slightly higher than the regular one since it has the quick release feature. On a side note, the quick release is nicer than the Arms ones on my Eotech 553.
Also this sight looks great and seems to be perfect for the Beretta Storm. I was hoping this would work out. I'll have to see how it is at the range, but so far it looks great, and seems perfect for this particular firearm (Yes I know it washes out in bright light).
Again sorry for the crappy pictures guys. I should really buy a camera one of these days.

Size comparisons between Tavor and other black rifles (Stag AR-15 and Swiss Arms have their stocks collapsed/folded, also the Storm has a longer non restricted barrel on it compared to the normal).
