Please recommend me a good fore end that’ll work with the 6 round side saddle (factory magnum foreend won’t work)-so far Google came up with Adv Tech? There’s got to be more out there, and I do have an email into the mfg of the side saddle…
Or a stock set for that matter…Thanks in advance 
Surefire, Speedfeed, and Hogue
THANKS!! Gonna call up Surefire and Speedfeed and see what’s compatible…
You could just pop your factory one off and trim it so that it will work;)
All you need to do is take a little notch off of the upper left rear corner of the forend. I should have explained myself more clearly. It does not end up looking crude by any means. Just hit it with some 400 grit sandpaper when you are done and it will look really nice.
It seems like I have to trim a BUNCH off the oringinal fore-end…Waiting for speedfeed to call back…
I run a Surefire with my 6 shell side saddle and it works great, plus you get the light which is well worth the price tag. I also have a Hogue over mold on my other 870 with the 6 shell and also no problems. They are both nice setups, but I want to replace my Hogue with another Surefire because their so good. Hope this helps.
This is the forend you need from Speedfeed at Brownells.
