I made it work with my 500... 12/08/2017
Ordered this set for my 3 year old Mossy 500 (gold trigger). I had read the reviews saying that some fitting was required, along with the need for a 7 3/4" action slide tube (for the M-LOK Forend) , but wanted to try... I did need the longer tube (mine was the 6 3/4" originally). to correct that issue, I ordered the Houge 7 3/4" tube with tube nut ($10 to $15 less than the one from Mossberg), and it worked like a charm (using the original slide tube nut).
The SGA Buttstock was an easier install, but be warned that the stock makes removal of the trigger group impossible without trimming the stock or loosening the mounting bolt.
The write up says this kit is for the 500, but the forend box indicates it is for the 590/590A1, while the box for the stock includes the 500 as a model that it will fit.
All in all, I love the finished product! Adjustable LOP, and feels better in hand. If you are willing to putz around a bit, you will have a very cool, and better handling gun. I believe the synthetic stock will hold up better when using the gun out in nasty weather!
Definitely recommended
Excellent 04/12/2016
Needed a shorter length of pull for a female user. This stock worked perfectly at its shortest setting (and could still be lengthened up to 2 more inches later for a larger shooter).
The ergonomics are improved and the new forend adds more grip for operating the slide.
Installation is very fast and easy as long as you know how to remove the original buttstock and forend.
