I am trying to mount a flashlight on a Mossberg .410 pump with a pistol grip fore end. I have been looking at mounts from manufacturers such as Brownells and all the others, none of them will say they will work, plus I have worked through all of them shown on Amazon. I want to mount a LED flashlight with a one inch tube and holding one or AA batteries, and have a button on side or back or remote switch, but not twist on. So far I have rigged up a scope mount for a 22 rifle to attach to the magazine tube and clamp a one cell flashlight in it. It may work, but I would really like a 2 cell set up. Having a .410 magazine tube really limits the options, there are plenty of setups for a 12 or 20 ga, but not .410. I need to keep the price of the mount and flashlight to under $75 so a Surefire flashlight is out. Pictures of where I am at so far are attached. If anyone can offer any suggestions on how to improve on this set up or has another idea of how to mount a flashlight on a .410 with a pistol grip, please let me know. Thanks, Ed.
