I want to get the ACE Skeleton stock and put it on my Bushmaster M-4gery that has the factory pinned collapsable stock already on it.

I noticed that the Skeleton stock advertisement states that it is for use with standard A1 extension tube, buffer, and spring, which IS NOT included.

Does anyone know if the tube, buffer, and spring that is on my rifle will work?

I have absoloutly no experience with AR type stocks and I am lost on this one.

I now realize that Bushmaster's Post-Ban fixed stock uses a full length buffer, and spring, so it looks as if all i need to do is get a standard Buffer Tube, any comments?
