I have never had a sight with a level until this year. i dont use it much, just another thing to take my concentration off the target.

have one, but it makes me panic when shooting if i watch the bubble and worry about being level. i agree, it SHOULD be level, but inside 40 yards (my set hunting limit) i never notice a difference.

to me anyway, checking the bubble just added complication that is not needed at hunting ranges for me.

I have one on my Spott Hogg, and it really helped me out when I first got it since I canted a lot. But it cracked or something and all the bubble juice ran out, but I don't really need it now.
