I've seen lots of info at this and lots of buzz at the SHOT show. My question is this? could someone buy a pre 86 full auto sear and build into an M27 IAR? thanks for your time

If I recall correctly, the carrier would have to be switched or modified. Completely ignoring the sear aspect, getting an HK upper to look AND function like an M27 would be an overly expensive undertaking in itself.

Re: HK MR556
If you wanted to go that route, it would probably be best to go get one of the actual HK 416 uppers that can be had (usually they are in the NFA length range but that doesn't matter with a MG) and put it on a registered F/A lower (non HK). Use the new recoil buffer / spring setup that comes with the 416 and you are basically there.
The MR556 upper and lower are both designed not to accept F/A parts / operation without a fair bit of metalwork.
I saw one for sale where someone had taken a registered F/A lower and cut in the HK markings so it made it look just about exactly like the military version of the HK 416, just if you looked really close, you could see the original engravings in black on the receiver as well as the new HK copied ones (which were in red / white)

Re: HK MR556
Another note is that the MR556 magwell is square and flared and as such doesn't work all that well with the standard BetaC mags or first generation Surefire mags etc, so going the existing registered standard F/A receiver and adding the 416 upper is probably a better way to go.
