Defiance Deviant Tactical. .308 bolt. I'm checking headspace and need to remove ejector. Anybody know what size/style punch I need to use? Roll-pin punch or standard flat-face punch? And is the process just depressing ejector plunger and driving out the pin? Will a typical Rem 700 ejector removal tool work on a Defiance? Something like this? https://www.sinclairintl.com/aspx/search/productdetail.aspx?pid=34592&sku=22-550
