How fragile are WW2 Garand op rods without the relief cut?

I know you are not supposed to shoot with these, but how fragile are they really? Anyone ever seen one broken? I know there are myriad of threads on this on the internet, I was more curious about files member experiences.

As long as you are not blasting off rifle grenades or shooting ammo in excess of 180 gr, they should be ok.

The modfied or cut put in garand op rods has nothing to do with firing grenades.
90 degree angles (uncut) are prone to cracks from normal use. The cut/modification is to prevent stress/crcks
I have seen a few over 20 years that broke in this area from normal use. Its not a everyday occurrence but it can happen.
I have a rifle with uncut op rod that I do occasionally shoot

Yep, 90 degree angles and steel don't get along. The Beretta M9 had the same issue with the 1st generation locking blocks. Now on the the 3rd generation blocks, there is a radius cut very much like the M1 op rod cut.

I have about 15 or more rods without relief cuts on resto's.

Dash- zero, -1, -3's,-6's, -9's, WRA, etc.
I do have a dash -2 with early relief cut and a -3 with a very early slight cut, almost unnoticeable.

Like shooting early low number '03's, have fun.

What Mr Banks said is 100% spot on.

A Schuster gas plug can help to soften the blow on any M1 rifle.

considering an unmodified op rod is worth twice an "improved" one to the collectors, I;d just sell it, put in an improved one, and laugh all the way to the bank.

Rare doesn't mean "better".

Info from Schuster site.

Quote:
Product Description

By adjusting the volume of gas in the cylinder it changes the speed of the op-rod and controls the harmonic vibration of the barrel. Our plug softens the blows on your op-rod and wear on the bolt lugs. Made specifically for use with heavier bullet weights and hotter reloads. Even if you only shoot your M1 once in a while make it last a second lifetime. Made from Hardened Tool Steel & Parkerized. Service rifle legal. Same appearance and configuration as the original. Conforms to CMP 12th Edition Rule 6.1.2. NOT legal for "as-issued" matches.

To make installation of your gas plug extra simple use our new M1 Wrench Set.

That, and shooting hotter loads than normal using standard powders such as IMR 4064. A common Garand load is 50.0 grs of 4064 with 150~155 gn bullets. This is a poofer load in a bolt gun, but it's a warm one in a Garand, the Schuster Plug is recommended to prevent early retirement of Garand parts.


Jes gotta include this every once in awhile;

Poem of the Garand

Do you wonder why that rifle
Is hanging in my den?
You know I rarely take it down
But I touch it now and then.
It's rather slow and heavy
By standards of today
But not too many years ago
It swept the rest away.
It's held its own in battles
Through snow, or rain, or sun
And I had one just like it,
This treasured old M-1.
It went ashore at Bougainville
In Nineteen Forty-Three.
It stormed the beach at Tarawa
Through a bullet-riddled sea.
Saipan knew its strident bark,
Kwajelein, its sting.
The rocky caves of Peleliu
Resounded with its ring.
It climbed the hill on Iwo
With men who wouldn't stop
And left our nation's banner
Flying on the top.
It poked its nose in Pusan,
Screamed an angry roar
And took the First Division
From Chosin Reservoir.
Well, time moves on
And things improve
With rifles and with men,
And that is why the two of us
Are sitting in my den.
But sometimes on a winter night,
While thinking of my Corps,
I know that if the bugle blew
We'd be a team once more.

Exactly! Or if you have it on a “correct” rifle, then have an extra to shoot with and keep the more valuable one aside for the investment side of things.

FWIW,

the M1 i got from CMP had the OP rod w/o the relief cut.

So what i did was to get one that did and install that and use it.

easy peasy.
