Quote History Quoted:The 86 ones fit A2 stocks I have perfectly.
I don't know if the A1 stocks changed over the years or A2 ones might have had smooth plates at one time.
The A2 drawing is marked 6 month of 82. I would guess anything made later might fit an A2 better than an A1. But that is just a guess off the print date.

Well I had to go check. I tried fitting a modern Colt A2 butt plate onto the A1 stock and it actually fit a little better and with a little less overhang in the same areas. However, I tried fitting the A1 butt plate on 2 different A2 stocks and it wouldn't fit. The A2 stocks are actually tighter and shaped a bit differently on the sides of the lower portions of the butt plate interface to where it just won't fit. I'm sure I could have forced it, but I didn't want to damage anything.
The A1 butt plate is actually a bit tight in the same area fitting it to the A1 stock, but not nearly so tight that they won't go together.
So at least for these 1982 dated A1 butt plates they're not cross compatible like the A2 butt plates are... I guess I should've just stuck with A2 butt plates across the board.
Now I'm interested to see how these A1 butt plates fit the A1 stocks from Fulton Armory.
