m14 norc vs usgi parts compatability

[45ACPKING]

I have a krieger barrel coming soon for a recently purchased norc m14s and have a few questions that i can't seem to find the answers for in the search function.

will the norc gas assembly.... gas cylinder only fit the norc barrels due to the threads?
i have a "quick connect vortex" flash hider, niw TRW bolt, usgi spec navy sight..... but do not as of yet have the usgi gas system and i need to know if this must be replaced or can the chinese assmbly be used.
I also see that brownells has these parts listed... anyone order these parts from them? I'll email and see if they will ship them

Chinese gas cyblinder should work fine. The threads for the gas lock are different, however if you have a navy sight made for an american barrel then you are good to go.

Brobee is right. The gas cylinder will fit, just the gas cylinder lock incompatibility. Now with your nice beautiful Krieger barrel, your flash hider castle nut will have to be a USGI one, because of the chinese metric/finer threads.

Does all this clear up your situation ?

So 45ACPKing.... who is doing your installation and headspacing to that fine TRW NiW bolt ?? Sounds like you are gonna have a mighty fine project there.

What a sweet sounding project !!

i haven't got as far as to figure how and who will do the work. I have the barrel vice and action wrench..... but i don't have a headspace gauge or bolt lapping tool. I'm not all that sure who is the m14 pro here in vancouver area as far as gun smiths go.... anyone recommend someone?
