Limbsaver Elite Prism site

[smagee]

Anyone using this site. I just bought one thought i would try it on my Z28 but it seems that the bubble level is not correct. It is one with the single adjustable pin. I have not put it on tried it and then took it back off.
It could just be me and the way i set it up just looking for some one who might have used this site?

thanks
Steve
