Hi all,
I have an opportunity to purchase this particular M1 Garand rifle.
Everything looks good including some drawing numbers being year appropriate.
The barrel is dated S.A. 12 - 50 with a very good bright bore.
My concern is the line down the middle of the receiver heel.
I haven't really seen this before.
Is it of concern?
Does it affect value?
It must be original to the reciever as the serial number and maker rollmarks are clearly over the line.
Your thoughts are appreciated.

I dont think it's anything to worry over. My Springfield 532xxxxxx has the same line, as does my Springfield 580xxxxx although its pretty faint on this one. It does look like the lower numbered rifles have a more pronounced line however.
The 532xxxxx is a Navy match and the 580xxxxx is a CMP 'correct grade ' and it didn't effect values on either of them. Nor the shoot ability.
 
If the rest of the rifle looks as good at the photo I don't think you have to worry about value. As far as an investment these are pretty good unless our .gov does something really sideways with the 2A.

Great guns and uber fun, enjoy.

And remember not all 3006 is good for that rifle, if you don't reload look for "garand safe" loads. Busted parts if you don't.....or change to the adjustable gas plug.
 
Thanks for that.
I will use Garand only ammo.
The gun does look nice.
I will post full pics soon.
P.S. I live in Canada.
I don't know if you're aware whats happening here regarding firearms but you would turn over in your grave if you did.

Schuster gas plugs allows a little more flexibility in ammunition choices. I reload all my ammunition to no more than 2700 fps ans use 150 or 168 grain projectiles and still use one, softens the recoil impulse and manages the brass ejection patterns.
Im saddened by the marxist trend in Canada and the inevitable loss of freedom always associated with authoritarian pukes like Trudeau.
 
Your loads should push a 150-grain bullet out to 2700 fsp, no more. High pressure loads can damage the charging rod so be careful what you shoot.
More false info.

M2 ball was on average 2800+fps at the muzzle. This 150grn limit or 2700fps limit is pure internet BS.

OP..note this "info" is coming from posters who know so much about garands that they call the oprod the "charging" rod.

No need for aftermarket add ons.

A properly lubricated rifle (greased) and one with an in spec oprod spring (19.5"+) can safely handle pretty much all ammo out there.

There is only one proper brass ejection pattern....from ~1230-130 on the clock.
 
The op rod is the weak link in the Garand. Excessive port pressure can cause problems with the op rod.

Powders for the 30-06 developed since WWII operate at the same receiver pressures but, in the Garand, the pressures in the barrel at the gas port can still be to high to be safe for the op rod. Hence, the development of the vented gas cylinder lock screws, aka adjustable gas plugs.

If one looks at an op rod, it is not straight. There are a couple bends in the op rod that require a special jig to form. Op rods can be repaired but repair shop needs to have the jig.

I’m not sure the availability of replacement op rods. 10-12 years ago I bought a couple for two Garand builds I started. I got two NOS barrels that I decided to turn into rifles. I have not kept up with parts availability since.

Since you mentioned it...

What is the port pressure operating specs and what is considered "too high" of port pressure in the garand?

Thanks

I know that your PM is trying to make all guns illegal. Foolish boy. As for the M1 I would not worry about it. Unless guns get banned it is not going to ever be worth more than you paid for it. Still it is one of the finest rifles ever made. I served in the USMC from Sep 1959 to Sep 1868. My first issued rifle was an M1. My second was an M14. My third was an M16. The M1 was my favorite. I do not have or need a rifle, but if I did I would have an M1 — nearly indestructible. Love your M1. I
 
Usmc 59-65 here. 0311 mos … Rifleman. Carried M1 first then M14 .never saw an m16. Of the two m1 was the best. That’s why I own one today. Mine is a 1943 Springfield Armory. I lived no more than 200 yds away from the Watershops Branch, and my grandfather, uncle, and mom worked there then so it’s a veery special rifle to me. One or all of them could have been part of its production. Mine is actually nicer than the one I carried in the Corps.

We put an adjustable gas plug in my friend's Garand. It shot all over the place with 30/06 Greek HXP from the CMP. groups never tightened up no matter what tinkering we did. Put the old gas plug back in and groups returned to normal. His adj gas plug is in the bottom of a box somewhere.

I know, been following it as close as every American should but few do.

Sadly this is not the forum to discuss real issues.
 
Please don't repeat internet myths.

PS there is no gas plug...its a gas cylinder lock screw.

Nice sharp shooting tex.

It is a common name, google it and you will find it.

There are times when using common terms will help people coming in new to things, shame you don't know that yet.....but then some people are like a dog that can not be taught to sit.

Let's use the correct terminology especially when there are new people involved.

Just because someone called it the wrong thing and everyone else continues that mistake there is nothing wrong with correcting it

Gas plugs go on gas trap rifles. Gas cylinder lock screw goes on gas port rifles.

Here is an interesting article devoted to M1 ' gas plugs ' , (that's what they call them too) wherein they cite the recognized authority on the M1 rifle, the CMP. According to quotes from the article from the CMP the pressures that common 3006 runs is ~60,000 psi, and that the recognized upper limits for the M1 is 50,000 psi, some trending to say 40,000. So in deference to some posters opinions regarding " can safely handle most any ammo out there" this differs, and in all probability again from recognized experts suggests that over pressures in an M1 may not be the safest thing to do.
Regardless of your ' feelings ' about ' gas plugs', it appears prudent to be able to limit the pressures involved with a plug vent, reducing the op rod speed and rearward violence of the rod and subsequent bolt action, while allowing the use of commercial, non M1 specified ammunition in bullet weight below 174 grn and not reducing through limited velocities the performance of the rifle.
 
I stand by my original statement that the Garand is well served by a 150 grain bullet and of course the 168grain that I did not mention. The muzzle velocities of 2700 fps are safe and accurate. 50,000 psi should be the upper threshold for pressure. Federal American Eagle for M1 Garand is 150 grain bullet shot at 2740 fps. Hornady Match for Garand 168 grain bullet is 2710 fps. Sellier and Bellot for M1 Garand 150 grain bullet is 2700 fps. PPU for Garand is 150 grain bullet shot at 2745 fps. The manufacturers and I agree on this. This info in from the manufacturers, I didn't make it up and it's not some internet thing. I did make a mistake regarding the use of the term charging handle instead of oprod or operating rod. Thats on me.

If someone wants to shoot hot loads out of a Garand then that's their business but better check to see what oprod type you have. There are at least three different types that were developed due to cracks forming at the right-angle portion. It required a relief cut to strengthen the oprod. The latter models were stronger but still not strong enough to handle a steady pounding of hot loads as the rods may fail.
 
My point is, and it is really a shame it needs to be spelled out is COMMON TERM. A person new to it would find what he is looking for.

Real shame some people can't understand that and their need to FEEL superior over rides common sense, but then that is lacking in great quantities with the people today.

It will likely be followed by someone running with tears in their eyes saying someone on the internet made me feel bad. We will find out if that happens in the future here.

OK..here is the deal..just because you print an article doesn't mean ANYTHING in it is actually factual. And this author doesn't really know much about this topic at all.

Just because you call it a "plug" doesn't make it so. Question....would you rather call it what everyone calls it or would you call it what JCG and the govt themselves call it? Gas trap riles have "plugs" gas port rifles have lock "screws". (see pics above)

This article and just about everyone else who "claims" to be an authority on this topic are still confusing pressure measurements... namely CUP vs PSI.

Up until about 1990 or so all measurements were done in CUP(copper units of pressure)... after that PSI (using a piezoelectric transducer).

SAAMI max pressure is 50,000 CUP
SAAMI max pressure is 60,180 PSI.

People see 50,000 in old books etc and forget it was done it CUP and now they go "HA! The garand can't handle it!" No they just don't understand what they are talking about.

I'm still waiting on someone to post the actual "good" garand port pressures and then post what an "excessive" port pressure is.


So until someone actually posts those numbers....everything else is a guessing game.
