Mine started out as a 28 inch rib barrel model but met mr hacksaw at the middle of the rib support right around 19.5 inches.
The next thing was the clamp on light mount, and longer screws to hold the light I had. A laser took up residence for a short while on the bottom rail of it but hung to low for my liking. As soon as I glued on the top green sight thing the laser was evicted.
It wore a pistol grip for a bit but was a little rough with 3 inch mag shells, so it was swapped for a top folding stock with no pad (and it couldn't have folded with the stock pad). That was equally brutal so it went back to the old factory stock.
The old factory stock was reinstalled with an elastic butt cuff on the left, and the shell holder was removed from the old top folder and screwed into the right side of the factory stock. Then I got the receiver mounted shell holder.
No sling on it, I got one for it as well as the mounting pegs but I haven't bothered to install it yet.
In case anyone is wondering it weight in at about 8.5 lbs according to my fish scale. That's with shells 12 winchester supreme 3 inch 00 buck, and 10 2 3/4 inch brenekee KO slugs. Sure that's on the heavy side but I figured if I was gonna add some lead weight to the gun to help with recoil I might as well have usable lead weights
This is my second Maverick 88, don't have a pic of the first one but it had a side receiver mounted scope rail and a red dot sight on top. The red dot was moved to another weapon because I didn't like how high up it set and a ring of fire turkey sight was installed on it. It retains the full barrel length and has only a butt cuff on the stock.
