I'd like recommendations on a reliable gunsmith in the San Diego area to mount a pic rail on my 870 receiver.  Thought about doing it myself but by the time I buy the tools I'd need I'll spend more money and still take a chance with screwing it up.  I'm not opposed to sending it out, as a second option - if anyone has a reliable smith with reasonable cost and turnaround times.  Thanks.

Check out California Police Equipment on El Cajon Blvd just west of I15... They were pretty backed up the last time I was there, but I was told that was because they were working on building a range at the same time, don't know if that's still the case but worth checking out.
