I'm doing an AR build with a new 5.56 barrell/extension (mated at the factory) and a very slightly used upper. I've got it all torqued down by-the-book. It chambers and chucks the action test dummy rounds like a trooper, but I don't have a headspace guage set. It turns out that they are quite scarce right now. I've done some reading about headspacing ARs and have run into a lot of conflicting opinions:
My gut says to go with the Army TM, but at the moment of this writing I cannot locate a field guage for sale anywhere. Has anyone ever seen an AR with a headspace issue??
- You always have to headspace check with go, no go and field guages.
- You only need to headspace with the field guage because that is what the TM says.
- You don't need to headspace if the barrell and extension were mated at the factory.
- You don't need to headspace if you are mating new parts.
- You don't need to headspace at all.
