Shotgun is an 870P 18" barrel. I'm going to get a Wilson +2 extension for it as soon as I can find one. I've been looking at this rail mount from LaserLyte: http://www.midwayusa.com/viewProduct/?productNumber=594799 I like the small rail type mount so my options to mount lights (or anything else) are open. Has anyone used this mount and have any opinions on it or any similar type setups? I don't need some huge, full blown rail setup as all I'll probably ever have mounted will be a flashlight or Streamlight TLR-1s. Also, I'd like to keep it on the mag extension (and without clamping on my barrel) so my forend is free. Thanks for any input.
