Default Rebarreling an 03a3

Iíve got an 03a3 that needs a new barrel. Not sure if I want to buy the tools and give it a go myself, or just spend the money and have a pro do it. Where should I send it if I want to have someone do it for me and what should I expect to pay to have the job done? Iím in San Jose and the only guy I knew that could do it for me is long gone. Iím half tempted to order the tools but I donít know if I want to deal with it myself.

Old military style guns usually have square threads, v threads are simple enough to grind lathe bits for, but square threads are difficult. I would recommend having it done for you. How far are you willing to drive out of the Bay Area? Cost wise I’d estimate 600 ish from a blank, more if you want it blued.

Iím gonna pick up a NOS barrel off fleabay or similar so I can try and keep the dates accurate. It should be a simple unscrew/reinstall and ream for headspace.

here is a barrel and the hand tools I doubt would be overly expensive to complete the job.
off the top of my head you would need go-no go gauges, barrel vise/action wrench, finish reamer, reamer extension, t handle and cutting oil.

If it has been headspaced to another receiver/bolt combination it may or may not headspace on yours. If it does not, I have US Ordnance test bolts to determine if there is a bolt "out there" that will. If it is NOS military or a Criterion it is short chambered and will have to be indexed properly and then head spaced to your service bolt.

If you had the ability to determine the length of the chamber from the datum/shoulder to the bolt face before you remove the old barrel you could answer all of your own questions.

You have to start by aligning the extractor cut, it is possible to screw the barrel in until it stops and then back it out and measure the gap between the front receiver ring and the shoulder at the end of the threads on the barrel.

Problems; the chamber could be too long or too short, and if the extractor cut does not align the shoulder must be cut etc. etc.

You certainly ought to be able to ship directly to CMP without using an FFL. Be sure to read over ALL the information in the provided links for details. One thing I noticed is that one must be able to purchase material from CMP in order to make use of it's gunsmithing services. Again, read and understand the info in the provided links. Everything you need to know is there.

Sounds like the OP is not familiar with the CMP or the eligibility requirements of the CMP for parts, ammo, rifle, or services.

Just keep it local

Service is not a transfer. You can ship direct to me and I can return it direct to you. I am an 0-1 FFL.

Blue: You can pick up a brand new 03-A3 barrel from Criterion barrels in either 30-06 or 308 for probably a better price than buying a new one. You will still need the barrel vise, action wrench, GO NO/GO gauges, chambering reamer, reamer holder, etc., along with the skill sets in order to do this job. Getting the headspace right is critical. Probably your best bet is to buy a new barrel and have kendog4570 install it for you.
