I'm looking for a rear housing with a rail on it. Anyone buy one and they are happy with it. If so where did you get it?

They all seem to require some fitting, and they get mixed reviews. I got mine from ebay.

The best ones are the side mounted ones.

I got one. To get it to work it took a lot of file and grinding work, but the results were good.
