I had the New Jones adj. Butt Plate installed on my BT-100 and am very happy with it. It has not moved from the original position since I had in installed about 2 years ago now. As said it will have to be ground down to fit your stock. Mine has the adj. screws thru the Kick-ezz pad to adj. so you don't have to remove the recoil pad to adj. the plate if you need to, when going to and from your gun case. Good Luck and Break-em all.
