After putting together the last AR lower I had a hard time getting all the "little" parts. Got an E-mail from MidSouth Reloading today and found out they have almost all those little parts needed even the c-clamp for the dust cover. Did not order all that I needed but $75.00 worth of parts. I am trying to get enough spare parts to finish 3 or 4 lowers (AR15). Next order will be for the bigger "small" parts (safety, forward assist dust covers). Those are not as hard to find.
