The most complete images of the adapter we've seen.

It is my understanding that the M249 "upper" in 5.56X45 used a rewelded Post Sample machinegun receiver as the "upper". Had he used something other than a Post Sample machinegun receiver maybe things would have worked out differently. BTW a M60 is a 7.62X51 belt fed machinegun.
