I have just found out through some back and forth e-mails with a customer that the Hatsan BT65 QE model will use the same LDC as the regular Hatsan BT65 rifle. I had a Galatian QE which I thought was basically the same shroud as was used on the other QE models, it is totally different on the BT65. So for those of you who have been asking about something for their BT65 QE rifles, they can use the same LDC as the Hatsan BT65. You should be able to just remove the factory shroud and screw on any 1/2 inch x 20 LDC of the same caliber, all the best, Neil.
