So recently picked up my Mossberg 835. I love the gun but hate the sights the rear sight is all over the place. I recently bought a Mount to put a red dot on it just waiting fo the red dot to come in. So my question is, How do i remove the sights that are currently on it? no reason to have a rattling sight when my red dot comes in. It kind of looks like i need to drill rivets out. Thanks every one. Also Does any one know where i can order the LPA trigger assembly? And a tactical/sliding stock (so my wife can fire the gun)? Thanks again.
