Rico, I used this NcStar rail. It has the advantage of having a sight groove down the middle so you can use the bead (or Bg Dot) sight with no problem.

I used a QD rail mount so I could dump the laser if it fails and quickly use the Big Dot sight. This mount has a locking lever and a locking adjustment screw.

Both appear to be of good quality with a low cost.
I mounted my laser directly to the rail. It's also very low profile. This keeps it more in line with the bore axis, for better accuracy. Raising it up too high means you'll have to compromise when it comes to adjusting it.
