All I know is that if you're going to make any changes to the receiver then don't post about it on public internet boards.
I really don't see a problem with it, but it's there for a reason, whether by mandate of the ATF or by HK to ensure import approval by ATF, and I'd rather not deal with changing the receiver when doing what Mike Otte does is a simple operation: mill the top off a full auto carrier. Or buy a SP5K specific carrier.
My preference always is: no permanent changes to the receiver. It's the expensive part.
It's easy to take off that little nub, but it's hard to put it back on.

I get it, but this kind of issue has been hatched out over and over again. What gets me is how some will advise you of what's "correct" because they are trying to make a buck. I've see enough examples to know the differences, but to each their own.
Well it's done. The SEF grip with my pack fits just tight enough to make it a solid high quality feel. I'll post a photo tomorrow. The modified bolt group is all good as well. About 30 minutes for the bolt carrier last night and another 30 for the grip tonight. Looking forward to testing it in full auto soon.

Want to switch to Spec contoured housing when available for mine. How do you get the trigger box out of the housing on an SP5K as the selectors on mine don't rotate up.
You mention switch to contoured housing so I assume SEF. SP5k has ambi pack not compatible with SEF housing.
