930 SPX forend fit
I'm not able to fully thread the mag extension on as only 5 of the 6 threads on the magazine tube are exposed.
I need to figure out where the forend actually makes contact with the metal on the gun and shave off about 1/8th of an inch.
I can either do this inside or modify the outside (front) of the stock where the mag extension meets so the mag extension has a recess to come down another 1/8".
What do you think? Where do I trim?
Yes, I've tried forcing it down farther, checked everything, jiggled and wiggled.
