For what weapon system? I've got a slew of Crimsontrace/Surefire laser/taclights on the handguns and a Trijicon TA33R-8 that sits on my rifle; it gets swapped out occasionally with an EoTech 555.A65 that usually sits on the Super 90. The M4 and both shotguns have Hellfighter Underboss taclight/laser modules.
