Hello everyone,
I have read a lot of good information that has been very helpful so far, but I have been having several issues with my 935. I am trying to build it for 3 gun, but it has been so unreliable that I dont know now.
I recently installed a Nordic Components MXT +6 magazine tube (10 total in the mag). I trimmed the spring to about 12 inches of overhang, but it wouldn't reliably load from the magazine at all with the 10 shells (2 3/4) in the tube. It feeds 8 from the tube just fine (sometimes) and other times it will just dump 2 or even 3 shells right behind each other into the lifter area creating a shell to shell jam in the lifter.
I read that sanding the shell stop lip helped with loading from the tube, so I sanded and polished it until it was smooth with no sharp corners and it still didn't feed 10+ shells into the shell lifter.
It seems as if there is too much pressure from the spring on the shell stop and the way the stop is integral with the bolt release button, it doesn't look like it has enough leverage to move the shell stop out of the way of the shell's rim. So I was wondering if there was anything else I could do to possibly get this thing to work the right way before I send it back to Mossberg.
Thanks for any help guys!
