What's a good visible laser for 12 o'clock rail mounting on an AR?

[RAM Engineer]

I'm looking for something similar to the Insight CVL:

I'd like:
1. Rail mount and offset for 12 o'clock mounting.
2. Remote pressure switch.
3. Green laser preferred, but not necessary.

Anyone have any opinions on the CVL or suggestions for alternate items?

Thanks,
Jason
