Has anybody tried the truglo holographic sights that are in the cabelas and bass pro turkey catalogs?
If these are the ones you are talking about then yes I have used them for three years now with very good results. They come camo or black. Truglo also makes the trupoint that is considerably more expensive but smaller. I have one of those on a hand gun and it has worked well also.

Truglo is also coming out with a new sight this year that you may want to check out. It looks like a good concept.
