Crimson Trace MVF-515 Green

[why1504]

I was at a trade show a couple of weeks ago and won this during the silent auction. Here is a link:

I got a good deal and it was for a great charity, the Fisher House.

I would love to hear opinions on this and how I should set it up on my AR-15. Range, etc.

The gun I plan to use it on is a S&W M&P 15T I picked up a couple of years ago.

I am also considering mounting it on my Colt 9MM AR. I will need to replace the forearm with one that has a picatinny rail I can mount it on.

All suggestions are welcome here.
