GTL-21 tactical light/laser sight
I have a GtL21 under rail tactical light + laser sight on my G19.. As many of you know the gtl21 sticks out farther then the gun barrell, about an inch. It can get quite dirty from all the gun powder after, or while shooting. The gun powder sometimes gets caked on there pretty good. What do you guys use to clean the lens? Any special product to use?
