Wanting to get opinions on having one lower and swapping out upper assemblies to essentially have a 2-in-1 gun.
From what I understand, when going from 556 to 6.8SPC I will need a different BCG, barrel and magazine. Is there anything else I would need that is unique to the 6.8? Any need to change or adjust the buffer system?
I am thinking for convenience it would be nice to have 2 assembled uppers instead of using 1 receiver and swapping barrels out. Other than cost is there any down side to this approach?
BTW if anyone has a complete upper in either 556 or 6.8 with 16" barrel, I am looking for one.
Thanks.
