thats awesome. i just got my red laser with homemade filter mounted on my AR-15. it is good out to 115 yrds with my nightvision. i got the filter idea from nightvisionforums.com. it is almost invisible to the naked eye but can be seen with my monocular. the filter is exposed 35 mm film, the really dark part, usually found at the end of the roll. work nice in front of a laser my friend.
hey good luck and happy holidays.
