Are there any "gotchas" (technical, not legal) in terms of compatibility of old M16 lowers and current M4 uppers? Or should I expect a pre-86 M16A1 lower to just fit into place with a Colt LE6940 M4 upper?
What about the collapsible stock from the M4? Could it also be fitted to the older M16A1 lower? I'm assuming I would need something like the Tapco "Collapsible Stock Conversion Kit" for fixed-stock rifles, but other than that?
Thanks!
Dave
