My pleasure. I hope it was helpful.
I have been using lasers since they were huge, heavy and not very practical. (Does anyone remember the huge American-180 units?) The LaserGrips for the M16 is one of the few lasers I still use. I have another one on a Govt. Model 1911. They both work excellent and there are no wires to get caught on anything. The battery life has been excellent and retention of zero has been excellent as well.
Another laser that just caught my eye is the new green laser from Lasermax. I think I just may be ordering one before the day is over. I used a green laser on a Garwood M-134G Minigun and even during the day it was easy to see. I didn't have a red unit of equal power to check it against but it seemed to be quite a bit easier to see than most of the red ones I have used in the past.
