M-1 Garand Question

Bucksnort1 · August 19, 2023, 05:28 PM

Gents and Ladies,

While watching a recorded documentary on the American Heroes Channel about the Marines in Korea at the Chosin Reservoir, I noticed a Marine firing his M-1 which has this ring like device on the left side of the receiver. It doesn't look like a ring for attaching a sling because that was done under the stock. The poor quality is because this was on my television.

Any ideas on this?

That's a new one on me. Never seen anything like that before.

It doesn't look like it hinges but again, it's an old documentary.

I doubt I have looked at one since the 1980's, so my remembered image is not good,

But that might be a base for a rifle grenade sight.

Looks like HiBC gets the cookie.

shows a section of the rifle receiver with similar ring and how the sight mounts to the ring which has the range markings.

ballardw,

He gets the cookie but one of my choosing.

It is the mount for the grenade sight base. There was a similar one for the M14 rifle as well. If I recall correctly the M14 one had a solid center and two holes for alignment pins.

since the rifles were not grenade only the grenade sight was frequently detached when not in use, and seldom put back on during combat, most often just estimations were used, learning the angle of the rifle for the desired "lob" only took a few shots for most people.

The squad's designated grenadier usually left theirs on, but most of the rest of the riflemen didn't. the sight was relatively large (it needed to be, to get the high angle for grenade firing), stuck out the side (what seemed to be a lot) and was relatively fragile.

being as it has no civilian use, the sights are uncommon on the surplus market and I think when the rifles were reworked (for civilian sale or military aid) the bases were often removed, but I'm not positive about that.

Just found this today and I remembered this post. Its a video from TFB TV on the Springfield M1a tanker. They show some pics of historical Garands. Look at about the 0:52 to 1:01 mark. Based on the commentary and a bit of googling it appears to me an M1E5 Garand, some sort of carbine, paratrooper, tanker model. Your items seems to be mounted in a different place, but it sees a lot more common on this model.

I also found this photo of what appears to be an old edition of american rifleman which lists it as a "M15 grenade sight mounting plate"

My first thought was it had something to do with a grenade ...
It isn't a pin ring ... but what is that ... I know I've seen it ...

BINGO ... HiBC gets the chicken dinner ... sight base - grenade launcher !

Just goes to show ... you get enough old guys together and you can get the answer to just about any firearms related question ...
I'm still clueless when it comes to women though .

Another vote for grenade launcher. Sarco used to sell them and the muzzle attachment. I should have bought one to fill out the collection of M-1 Garand stuff when they were cheap.

The sight itself is pretty cheap, $16

I'm no spring chicken, but I had never seen that accessory for the M1 rifle.

Stuff you learn here .........well done all.

The city I live in used to have a true,old school surplus store.
It smelled like a surplus store.
You'd find bins of about anything there. GI bore cleaner, mosquito repellent,web gear,mostly WW2 vintage,

They had a bin of the grenade sights, complete with the original pouch.
I didn't figure out a real good use for them.

Man I really miss those old school army surplus stores. Loved those places.
