Mossberg 500 Upgrade and MA Compliance

[FN atic]

Hey Everyone

I've been entertaining the idea of converting my pump gun into the home defense gun. I've done a bit of research into what MA allows and seems like as long as it is a pump action and cannot hold more than 5 shells you can do whatever you want as long as it doesn't violate NFA. Am I completely wrong here?

With this does anyone have experience with similar builds and recommend anything I am not including or anything seem to be a waste of money? I'd still like to take it to the range from time to time but mainly will be for the bump in the night.

-Pistol Grip and Scary telescoping/folding stock (if allowed)
-Polymer Handguard with Vertical Grip
-Pic rail adapter for light and red dot
-Backup night sights
-Laser

skip the tacti-cool

18.5 inch barrel, +3 tube , pistol grip with adjustable stock, Pachmayer or other furniture, a sling type device on the pump keeps your hand from sliding forward which is a concern with short barrels.

If you want lasers, rails, lights, etc etc etc keep a pistol next to the shotgun

If you could find the old folding over the top Remington police style stock even better
