Outside diameter of milspec ar15 buffer tube?

[URGILOVERR]

I need to know the outside diameter near the butt stock end for a mil spec receiver extension. Does anybody have a link to the TDP I can take a look at for myself? Or does anybody know?

Thanks but a A 1.14_what? I’m measuring 1.1450-1.1455 I saw somewhere someone said that it’s 1.1485

I think it can be between 1.145 and 1.150
