Mine locks up well. You can adjust the tension with the round adjustment dials on the opposite side of the levers. I've had this for four years. The way it's setup I don't rap my knuckles on the levers and the regular charging handle works great.
That being said I have a couple ADM mounts on AR rifles and they are nicer. More expensive but it is my favourite mount. The Burris works decently, is cost effective but not as nice of a product.
Well that is the reason I might own one again....
