Norc internals in USGI bolt

[I <3 M14]

Are there any issues with putting norc internals in a usgi bolt? Thanks.

I'd use USGI guts if available, on the grounds that the Norinco ones have been known to be soft and wonky dimensions. However, if you search CGN for Different and go to his homepage, there is a weighty great on-line book that has several pages on the similarities (and differences) between the two makers' outputs.

For the most part it should be okay, and there is no soft parts issues related to bolt guts that I have observed.
However every bolt may not accept the parts. The most important thing is that firing pin protrusion, overall length and firing pin hole dimension must be guaged to know if the firing pin is compatable
Extractor and ejector are compatable
Norc ejector spring requires 3 coils cut
Norc extractor spring requires 2 coils cut.

What is the best way to track USGI bolt?

Best place I've found is right here on the EE... just watch it like a hawk because they usually go fast.

What the Dr said ! The springs tend to be on the long side when compared to USGI. Believe it or not, I have found the Chinese extractors to be far superior to what Sa inc is using in their builds .
