I guess we should start with the cheapish option, which could be to use the Excaliber rangefinder mount:

if you read the disclaimer it says for use on crossbows and rimfires so for airsoft it should be fine.
If you get a little extra cash for Christmas though :wink: Burris and Nikon both have laser scope available but expect at least $600 (double for the Nikon, although the funny thing is that they look exactly the same).
