Tried the IDZ stock on mine, but eventually went back to the G36C stock with the cheek piece. The fact that the IDZ cheek piece is curved and fixed forward on the stock meant that I needed to have the stock retracted to get the proper cheek weld, which then meant that the ejection port was blocked with the stock folded. The height/position of the cheek piece and LOP on the G36C stock just worked out better for my situation.
Also went back to a standard K forearm from the slim aluminum HKey forearm. I guess I'm more into the retro G36 look than the new HK 243 TAR look.
