Bushwacker makes flip up covers for scopes and also market the smaller size, #1, as mini-mag covers. I've found them in red, blue, and yellow and been using the red one on my L-1 since before SF started selling them in this cofiguration. They've proven to be very usefull and rugged in my experience and with something like the L-1 you get two levels of light in each color. Also the bushwacker is about 3-4 dollars cheaper for the exact same thing. They also will fit on an A-2, although it's a tight fit and may constrict the beam a little, but not that I've noticed.
