I have a few questions for building a M4/M16 first off I have a FFL IN MANUFACTURING AND CLASS 2 SOT so for me it's legal for L.E. demo purposes, and research and development. With that out of the way this is my first M16/M4 build, I just bought a 80% blank completed receiver, which I will machine it to accept the full auto sear for the build. Now my question is what all parts do I need to finish the build? I assume I need M16 full auto sear, trigger group and bolt carrier. Is this correct or do I need more parts? Thanks guys for the info. Please no replies about this is illegal I am approved thru the ATF TO BUILD MG's.
Op, since the information you request is neither a State secret or illegal, in fact, it's posted on the ATF's website, if you dig deep enough, here it is:
Trigger
Disconnector
Hammer
Sear
Bolt Carrier
To the rest of the posters in this thread:
That is all you need. Knowing that information is not illegal. Nor would be telling someone the list of parts. It would simply be illegal to take that information and attempt to build a machinegun unless properly licensed to do so. Even if the BATFE wanted to fish for dumbasses, asking a public forum what parts constitute the necessary parts to make an M-16 wouldn't be they way they'd go about it. In fact, being given the correct answer in an intelligent manner would actually reinforce the fact that they are doing one thing right - educating the public about what parts they can't put in their semi-auto weapons (with the exception of the bolt carrier). Loosen the tinfoil, folks.
