CASV or CQBR?
I'm looking to upgrading my M4 with a new frontgrip so I could mount flashlights and such onto it.
I'm still new and none of my friend knows anything about M4s because their new too.
So here does.
What's the different between CASV and CQBR? and which is good for what?
Also, I found that Mad Bull mainly have CQBR and King Arms have the CASV.
Mad Bull's product is cheaper than King Arms, but their made out of the same materials, why are the price so different?
Another thing, can the CASV and CQBR carry mini type batteries? Or do I need to get an external battery kit?
