Well, 1st post. Really enjoyed lurking for awhile. You folks seem to know your stuff, and I appreciate the forums. I have a Remington 870 express, "tactical", 18" barrel, purchased during the scare of '09. It is currently nestled on a bed-frame cradle 1-2 feet from my left arm. I would like to place a flashlight mount on it, but noted that most of the decent mounts require an extended tube, of which I have the dimples and probably won't retro. So, I don't want to spend $300, but and willing to spend maybe $30-50 on a mount and maybe another small chunk on a light. Any suggestions on either?
