I was looking at one of these last week at a local shop. I was messing around with it and it is a little bit heavier than the CAR15 collapsible stock on my gun now. Im not sure if you'd notice the additional weight that far back, as most of it is being supported by your body, and not an extended arm. It did seem pretty sturdy though, sturdy enough to smash through a door. All in all I liked it, but it was a little pricey for my tastes.
