Its a stationary grip. Its more of a reference for my hand for repeatable placement to allow easy access to my light. I like the argonomics of it. I have yet to use a magpull product i didnt like. I thought about a vertical w/bipod but in reality there probably will never be a time for work that i set up in the prone with bipod. It will be 99.9999% stowed so i passed on it.
