looking for specs on carrier groups,Why cant find?

[hambone2]

I understand what you are saying. I just thought it was odd that both the upper and lower blueprints were readily available for download in a bunch of places, and that every place I saw did not have the small components of the gun(with dimensions). Even on sites that specialize in milling & making their own firarms.
It was just a questions really, I mean its a heck of alot easier to spend -$100 on a lower, than to machine one yourself. I guess some things are just "the way they are".
Any how ,thanks for your input,I like the site...
