Im thinking of going carbon fiber with a bolt together lower like one I did in stainless a while back. I need another AR for the old lady to shoot but this one will be a dedicated .22 (shes complaning about how heavy it is.) So heres my question how hard is this stuff to machine and how strong is it really. Do you think it would work well as a bolt together? Im thinking of carbon for both the lower and the tube for a custom stock. Ive never worked any carbon fiber so I have no idea about the stuff. Thoughts??
