I use it on my Metabo/Hitachi NR90AE(S1) nailer when installing fairings. I mostly use it as a damage free option instead of the small hard plastic/synthetic rubber options you can buy specifically for this gun which wear out too quickly and keep deflating as they wear out. Thing is, you don't want to use set screws to flush mount this front to your gun if you're also going to be using it for framing. So, of course, the advice is to use thumbscrews, but they tend to come loose quite often…
