Garand question

[ksjsms]

Hi, I am a carbine guy but I just received a couple of CMP Garands that I am putting away for my sons. They are both service grade from Springfield Armory. One of the guns has a round metal object screwed into the stock on the left side below the receiver area. It is about 2 inches in diameter. The best way I can describe it is that it looks kind of like a cereal bowl with a quarter inch lip around the top of the bowl. It is graduated with the numbers 0 thru 60 on the lip on twice across the bowl from each other. This may be the worst description ever but it is the closest I can get. I would like to know what it is and what it does to the collectibility of the gun. Thanks!

It is the base that the grenade launching sight would attach to. The numbers are the degrees of angle the rifle would be set at. The sight had a pointer , you'd spin it to the degree you wanted , then leveled it with a built - in bubble. There are two sets because 1) both side would be "up" on installation and 2) some guns would be fired ( with the butt on the ground) up-side-down to prevent stock breakage ( folding stock carbines come to mind).

The "round metal object screwed into the stock on the left side below the receiver area" is the mounting plate for the M15 rifle grenade sight. It unto itself has little value. A complete M15 sight goes for about $10.00 new in wrapper and pouch. I have seen M1 rifle that have had the base plate removed and the holes filled. This was done by the U. S. Army and was NOT a civilian repair. By the way the M15 sight was also used on the M1 Carbine.

I have got to learn how to type faster!

Thanks guys very much for the information. I looked at it and looked at it and never came close to coming up with a grenade launcher base. Also, in all my dealings with carbines I have never seen one on one of those either, so I'm glad to learn that too. I appreciate the pictures as well. It helps alot to see it together with the rest of the grenade launcher set up.

Also used on 1903s and 1903A3s. Mostly these during WW2 because the launcher for the M1 took a while to develop and while it was on it made the Garand a straight pull repeater ( as well as screw up the POA) and the constant on/off often resulted in the launcher's loss. The carbine was used a lot in the pacific by the marines because the different gas system allowed it to fuction with the launcher attached. The Garand launcher that allows semi-auto fire while attached did not become available till post-war. Chris

I saw one also on a 1917 Enfield.
