if you wanted a light system . this is a great one....best of all.....it is attached to verticsal grip in one piece! reallt great if you got a rifle that has alot stuff on it....the vertical grip lets you hold on to it better. the light is very strong! good enough for your CQB skirmishes.........i put this on my classic army's SCAR. for those who has one.....knows it can get heavy during play!
