Kelly Front Sight

[Nuclearcricket]

Hi All, I just picked up a Kelly front sight. I got a good deal on it. I was wondering if anyone has any experience with these front sights?
To me it seems to be very well made, crisp edges but not sharp, no burrs, everything seems smooth. The only thing I have a small concern about is the size of the bubble in the level. To me it seems a bit small but that is just a casual observation at this point, will have a much better idea once it gets mounted on a barrel. The one I got fits a standard 3/8 dovetail.
Thanks in advance.
