Rem 1100 stock replacment question

Instead of a long bolt, it's a short nut with a slot in it for a screwdriver.

The 1100 has a recoil spring in a tube, running down the buttstock, kinda like an AR-15. The spring is retained by a pin; if there's nothing wrong with your 1100, all you do is get a long, big screwdriver and unscrew the nut. Under the nut, there's a lockwasher and, in a wood stock, another washer with a couple little spikes that grab the wood to protect it from the tightening nut and lockwasher.

At the receiver end at the base of the buttstock, there's a metal plate that fits over the spring tube and into the back of the receiver. You don't have to do anything, but if you drop the thing, that's where it goes. Just slide it back on.

The recoil spring doesn't come out; it's not held in by the nut. The nut just holds the stock on. Easy as pie.

I have two buttstocks for mine, one stock length and one shorter for my wife or a kid to use the gun. I swap them occasionally, no problem.

Does the synthetic have the spacer that the wood stock uses?
I know I had to remove mine when I swapped from wood to plastic.
