I did build mine up under the tactical works stock cover which by the way is a very nice piece. I just used two layers of 3/4" felt off an old saddle pad and I like it. I ordered some 0.187 kydex to make something permanent and then I will put the tac works cover back over it with some 1/4"felt or neoprene between it and the kydex for a slight bit of padding.
