I have a .308 SPS and a Bell and Carlson stock. I bought a Stocky's M5 DBM and had a smith install it. He called today and said he was afraid to go any deeper because he didn't think it would feed properly. I took it home and installed the bottom metal on the action and it seemed fine so I'm not sure what he;s talking about. The front screw seems to be almost flush while the rear is clearly not deep enough. Since the outline of the DBM is perfect can I just deepen the two inlets? Everything is lined up perfectly. just not deep enough. Any idea why he thinks it won't work?
