Honestly I'm still going to stick with MKE/Zenith because they don't have that horrible block where the front trigger housing pin is supposed to go. I honestly could not care less about the block in the receiver that prevents a full auto bolt carrier from being used - I never plan on buying a registered sear anyway.

Sounds like a fantastic idea. For whose who have SBR'ed their MP5 and engraved the upper, I guess the SD upper wouldn't work with a stock, would it?
Somebody correct me if I am wrong. The SD upper is an excellent idea. I just want to make sure it would work with a SBR'ed MP5 without violating any NFA laws.
