How bright is the XS tritium blade front sight for AR-15's? Do they stand out brightly or are these types of sites pretty dim?

I have the 24/7. It's more of a post-type than a dot, but it is very bright.

Do you only get one of four adjustment positions or does the vial somehow rotate?
Thanks.

i agree that it is very visible in any light conditions. definitely worth getting one since you get almost as much utility as some of the $500+ optics without adding weight and without killing your wallet.

you do only get the one notch for elevation adjustment but you can make up for that with the tiny allen set screw on the rear sight's elevation wheel. ashley includes a set of instructions on how to do it.
