hi thanks for getting back to me, the bolt you sent me is to short when pressed in the back position it only sticks out 5 mm when it should stick out 19 mm. I know this as i already have one, the one in the bottom is the correct one and the one in the top picture is the one that you have sent. I think this is the DM 5 bolt as it is shorter. You have sent me the wrong one. If you send me an email i can send you a picture.
Thanks Matt
