LWRC parts interchagability question

[Bennyboy]

Are the parts in a LWRC the same as a standard DI AR (obviously outside of the piston system)? The lowers, triggers, all interchange--in the lower but the upper--where the difference is. Obviously the BCG from a DI to a LWRC is not swappable, that's NOT the question, the question is on the firing pin, and other standard parts, pins, etc in the upper. For instance, could you swap a bolt from one carrier to another? Extractor?

I know that somebody has to know the answer to this question.

I have an LWRCI M-2 and it uses a standard bolt, cam, key, and firing pin in their proprietary carrier.
Some models have the enhanced bolt with the different size and shape extractor. Mine was enhanced but Ive used a standard bolt in it as well.

I was afraid of that. I was wondering about spare parts. Thanks for your help.

Maybe i wasn't clear. All BCG parts are standard AR except the carrier
