    I just received my breech today. Very nice build quality. I inserted my .500 OD .357 TJ barrel, and perfect fit. Cocking the bolt is done by a knurled knob and not a bolt handle, so I will take a bit getting use to it. Only qualm is that the bolt doesn’t fully meet & seal the barrel. So I had to unscrew the bolt probe and add extra rubber gaskets, but that seems to have fixed. All and all, I’d buy another one.
