How do you get the gas plug you have out to clean the gun now??
Got a screwdriver or combo tool?
You just screw the old plug out and screw the adjustable one in.

sounds simple enough, thanks

Piece of cake as noted above. The only part that takes any time is adjusting to the ammo the first time--back off until the rifle fails to cycle and then tighten down until the brass is flying the way you want and the hits are tight. Remember how many turns to reach the setting if you want to use the original and come back without spending setup time.
Guy, are you using a McCann adjustable gas plug? The Schuster has a set screw which is used to adjust the amount of gas that bleeds out. Once it is adjusted, you tighten a locking set screw on top of it. That adjustment doesn't change when you screw the adjustable gas plug out to put the original back in. Once it is set for the specific ammo, you can switch the plug in and out with needing to adjust it again.

Your experience with the shuster plug is directly counter to mine. it's very difficult to remove without changing settings.
I don't know why you would find it difficult to remove without adjusting the setting. The setting is adjusted using an allen head set screw. There is a locking set screw that prevents the adjustment screw from moving. To install or remove the gas plug you use a large slot screwdriver.
I'd like to know more about how removing the gas plug could change the setting.

The Gas setting I have to use is very open. the set screws intrude into the screwdriver slot.
Okay, I understand now. Are you shooting heavy bullets? I've only used 150 gr modern hunting ammo and not encountered that problem. I'm just curious about the situation in which I might encounter the same issue.

I'm using it in a tanker garand with an improperly sized gas port.

Why would you want to return it to "original" configuration? That's reduced loads, right? Why wouldn't you want to always shoot standard loads?
Full open factory setting on a Schuster plug sets the screw half way into the gas screw and allows plenty of support area to easily remove or install the the plug.
If somebody had to back that screw out more than factory setting, that plug isn't helping and the shooter will likely blow the set screw out especially since there is no room for the lock screw OR, they have the lock screw in place which is reducing the amount of grip space on the gas screw.
If that ain't it, replace the barrel because that oversize gas port is an accident waiting to happen

I can't speak for others, but I keep the original gas plug in most of the time because I want to shoot M2 surplus most of the time. Surplus ammo is much cheaper than the hunting ammo I use. I switch to the adjustable plug when I want to use hunting ammo. It is much easier to switch between the two plugs than it is to change the setting on the adjustable plug.

Much, much easier to forego the adjustable gas plug, and just buy yourself some 4895 and hunting bullets.

Well, one can't always count on a stash or reloaded/handloaded ammo being available and the adjustable plugs make finding suitable ammo easy.
It is a good bit to have in one's personal kit if they are inclined to own a Garand or two.
Oh, once you get an adjustable gas lock screw properly adjusted, it doesn't matter which rifle you use it in.

I'm planning on ordering a cmp Garand this week. Where do you get surplus ammo? Is it made in the US or is it corrosive?
Finally, do the clips come with it?
Reloading wouldn't really be easier for me. I don't hunt with my Garand often, so I don't need to spend a lot on hunting ammo. Buying the dies would pay for all the hunting ammo I'm likely to ever purchase. Then factor in the time. With small kids at home and work responsibility it has taken me over a year to work up a load for my .300 win mag.Much, much easier to forego the adjustable gas plug, and just buy yourself some 4895 and hunting bullets.

You can purchase the surplus ammo from CMP:

You want to look for "en bloc" ammo. That means it is loaded in clips. Looks like CMP is sold out for now. CMP still has Greek HXP ammo. It is not corrosive and is good quality, accurate ammo.
