Ya I know, I bought their PEQ which isnt a battery box...quality is pretty good, and very very BRIGHT and long distance laser...I'm gonna do a review on it later on. =D. So yea, just trying to get my hand on G&P accessories at this moment for my M4, other then the crane stock, any opinions what I should get for the Marui M4 RIS?
