I have a MOssberg 930 SPX with the LPA rear sights and fiber optic fron post. The gun is all stock. I could not get it to hit on a piece of printer paper at 25 yards yesterday with value pack Remington slugs. I have the rear sight cranked all the way down and it is still about 12" high. Has anyone else had issues with this? Does anyone have suggestions on what to do? I know some people have had issues with canting on the front sight but i am all centered up. I think I might be contacting mossberg. There is no point in pay $600 for a gun that you cant hit a piece of paper with.
