Hi, I'm new to the Garand and have a question.
The action is not cycling when firing.
The gas port is clear and the action moves easy by hand. is my gas chamber worn out?
This is an old rifle.


any help is great I know that without seeing it you can not give a perfect answer and no one is a gunsmith giving ad vice just looking for some recomendations.

could be a few things;

-bad ammo lacking the right pressure curve or under loaded

-gas cylinder plug is loose or it's vent plunger is stuck open.  (it opens when a grenade launcher is mounted on the rifle)

-poor piston to gas cylinder fit; either or both excessively worn

-bent op rod or stock fit interference issues

-or very commonly lack of proper lubrication.

What exactly does it do when fired? Does it start to cycle, or ???

It does not even flench. which is why I figured it was poor fit between operating rod and gas cylinder.
just from the looks of it I figured the gas cylinder was worn
the cylinder plug is tight. the ammo is factory.
this is a old gun.

does anyone have specs on the OD of the rod? or ID of gas cylindr?

it feels well lubed when had cylcling. But like I said I'm new to the Garand.

thanks for the input.

I figuer I should start by changing the gas cylinder and then see how it goes.

Specs on the cylinder and a troubleshooting guide.

Gas piston: 0.525" min. o.d.
