This is a great add-on to your Knoxx stock. I really like the higher (and more comfortable) cheek weld that results from using the "high" cheek piece.
The install is a little awkward with the supplied ball-end allen wrench. Overall, it is not difficult. This item gets my 100% recommendation.
Pros: Better cheek weld, useful shell holders, tough material
Cons: Install is a little tricky
