Default M1 Garand Barrels

I've got an M1 Garrand that shoots but...The barrel has been cut off an inch, sometime in it's life and the bore is none too good.
I would like to find a barrel or a couple of them and the receiver blocks to change the barrel out. The original stock sits in a cabinet. It wears a new walnut stock with some figure. I probably need to replace other parts but haven't miked them. I hope the receiver is in spec. Would like a machined trigger group. This one is stamped housing.
Toying with changing it over the .308 magazine fed rifle. Parts are avaialbe but no in budget right now. I understand the early version was intended to have a magazine feed but some wisenheimer though troops would waste too much ammo. It would be nice to find the info and blueprints.
Help

Cutting an inch off of a Garand barrel would remove half of the threads for the gas lock. It would also destroy any chance of getting any real port pressure to the gas cylinder, making the gun a straight pull bolt action - no matter what the bore condition was. So forgive me for not taking this claim at face value.

Plenty of barrels available out there (I use Wilson) as well as barrel vices, receiver wrenches, alignment jigs, chamber reamers etc., etc. All it takes is money..... and lot's of it. Oh, and you can simply swap out the stamped trigger guard on your Garand with a milled one. No need to change the entire trigger group.

Save the old barrel and put it to good use. Cut off the chamber end and make yourself a bolt lapping tool.



I have 4 Garands and have never once considered converting one to a ".308 magazine fed rifle". That's why god invented the Springfield M1A rifle.

Seriously though, I have all the tools and gauges to do it but in the long run it's much cheaper and easier to just buy the M1A and have a better gas system to boot.

JMHO.

I didn't measure the actual amount that was removed. I haven't had it out, of the gun cabinet, in a while. Everything is there but the barrel is a little shorter or appears to be.

Fair enough. I know trying to work from memory myself these days I've got about a 50/50 chance of it being right.

Not sure why anyone would change a Garand over to .308, but I'm sure it'd be possible for the truly determined. Have you looked in the usual locations for a replacement barrel? Sarco, etc.?

Are you sure your barrel has been cut down? Have you tried simply recrowning it? Have you bore scoped to check condition? Headspacing? Anything?

It's normally done to create a "tanker" (shortened) version of the M1. A spacer block is installed inside the receiver to allow feeding the shorter .308 rounds and prevent loading of .30-06 rounds. Think of it as a "scout" Garand.

The CMP sells new Criterion barrels (Krieger subsidiary) in .30-06 or .308 for $190 - $200 delivered, respectively.
Converting to a detachable magazine is a whole 'nother can of worms though.

True that. You can't help but admire a guy that floods his living room in the winter so he can ice skate when he wants to. I suppose most geniuses have there eccentricities though.
