John,
I dug a little deeper into this last night including looking back at several of Matt Williams posts from here (he used to post as triggerguard). Still not finding anything on Williams aluminum one piece bottom metal for m70 classics. Can you post a link where you have seen them or seen them discussed? I would be quite interested as I have a couple McMillan’s that are inlet for the Williams bottom metal and I am always looking to shed some weight from m70s - although I’ll acknowledge that finding any Williams bottom metal since the closure is nearly impossible.
Thanks!
