They just delivered my M1 Carbine Inland Barrel and I'm ready to put it on. I was reading my Gunsmith Books that I have and even though I have the tools I think after reading and watching a few Videos I know there's more to it than just lining up the marks. Has anyone changed out a M1 Carbine Barrel that might have any pointers ?
I've done one and it wasn't easy. They can be really tight and you need to protect the barrel and receiver from being damaged. I took a lot of time with mine and had the barrel blocks in a 20 Ton press with a lot of force applied. I had to use a cheater on the wrench. The press wasn't bolted down, but should have been. Some are easier I've heard. You should be able to find some good advice by searching our website. Is the hand stamp on the receiver shown in photo #9 what it appears to be? - Bob
Looks like it to me.
Yes...It's been de-milled and is cut in half. Everything about the Barrel is l Nice. I know I won't be able to find anyone here. We don't have a Gunsmith that works on WW2 USGI Firearms and don't know who to send it to. The places I called here doesn't do M1 Carbine Barrel Changes. I need someone I can trust and the Barrel won't suddenly go missing.
If you have a large bench vise (5" - 6"), you can take it off yourself. First, soak the area of the barrel where it's threaded into the receiver with penetrating oil. Patience required, I usually do this over a 5 day period. Keep giving it PO, and tap the area with a brass or lead hammer. Heat is good to, like a soldering torch, but just a little heat, til the oil starts to smoke.
If the receiver is scrap, then you don't have to worry about damaging it when you attempt to take this apart.
Clamp the barrel, by the "flats", in the vise horizontally, using brass or aluminum shims, so the steel jaws don't damage the barrel. Be aware that the gas block can have a bigger diameter, and the shims must be at least thicker so the jaws don't touch this area. Tighten up the vise as best you can.
If you don't have a M1 carbine receiver wrench, then you will need a large adjustable wrench, and this is clamped on the area of the receiver where the lettering is. Try to get this as tight as possible. I have found you need to use an impact to loosen the thread, not steady pressure. It's been screwed together for 70 years. I'd use a small steel sledge hammer to hit the end of the wrench. The wrench will come off, and may have to repeat this procedure. (make sure you hit it so you are loosening , not tightening....as funny as that sounds I have done that as part of the learning curve.)
I can also suggest using a Dremel tool to grind 2 longitudinal slots in the receiver ring, down just to the threads of the barrel. This would be tricky, but would effectively remove the receiver from the barrel.
Putting this barrel on another receiver is a little easier. Same clamping of the barrel in the vise. If you have to use an adjustable wrench, use brass or aluminum shims between the jaws, so the receiver is not damaged. Less force is needed to tighten, and line up the index marks best you can. Don't use the sledge. M1 carbine manuals show how to use the parallel bars to align correctly.
It is really better to have the proper receiver wrench.
To insure this is a safe assembly, check headspace with your bolt and GO, NOGO gauges.
Hope this helps
Manteo97, I sure wish you live here in the States....I would send it to you. I know it will be a FEW bucks, but worth it. I don't want to damage either of them.

Does that also mean an M14 or M16 are not NFA weapons if I don't put any FA parts in them? Or, does this only apply to the M1/M2? This is, of course, a rhetorical question ;)Quote:

I would caution anyone using any site other than an official BATF&E site for reference regarding these. The receiver of a weapon is what it is/was. In other words, once a machine gun, always a machine gun. Now, as to Frank's "chopped" receiver, he's more than fine :)

Thanks Bob and ALL the others who replied to my post and sent PM's and emailed me with ideas and for help. I just received a phone call from Chuck and he told me things I did not even think about. Like one Major thing is the Spring Tube. Many People forget about it and crack it when doing a barrel change and then your really up the creek. You don't want crack a Hand Stamped Receiver, you just lost a lot of Value if you do, then you got to find one which is almost impossible to do and just go with a regular receiver. The price for the tool I was going to buy is 3/4's of what he will charge to do it right. Thanks for the replies and help. I'm not ready to do this swap. I would if I had a inexpensive Carbine to practice on and it didn't matter if I screwed it up. It wouldn't hurt as bad. Thank You.
