Hey there.... I would like to have D-rings on my Behind Barz waistband. I just doubted a lot with D-rings I should use, because I didn't want them too small or too big. I ordered on aliexpress a few D-ring in a size 20mm. Last week they came to my house and yesterday I made them on my waistband. It had to come off for cleaning anyway. On the sides I drilled 2 holes of 5 mm width and mounted the D-rings with the tiny screws from Behind Barz witch I had on spare. On the back I did the same, 2 D-rings on existing holes from the back plate. First I thought the D-rings were too small but when they are mounted on the waistband I think it is a perfect fit. When I have enough of them, I just unscrew them and the only thing you ever see are 2 tiny holes on the sides. Total costs: €5 for the 10 D-rings and 15 minutes time to mount it....
