How far out does a collapsable stock (M4, CTR, ACS, etc) have to be, to have the same LOP as a A1 buttstock?
I need to know for a build I'm thinking up for my wife.
Thanks.

A standard M4 stock (one that is flush with the rear of a mil spec receiver extension, or close), will be the same length as an A1 stock fully extended. A SOPMOD or ACS will be about the same at 3/4 out.
