I'm going to add an adjustable gas plug to my DCM M1 Garand. I see that there are several different ones out there. Do y'all have any suggestions for which one to consider. Is there one I should avoid? Mine is currently as-is from CMP.

Begs the question: why? Plenty of Garand-compatible ammo out there, not to mention ease of handloading same.

I've got an urge to experiment.
I've got a couple of loads-- one a hunting load with 165 grainers and a target load with 150 grain FMJ's. These aren't hot loads, but from what I understand, I can tune the rifle by adjusting the gas.

Garandgear.com has a gas cylinder plug that works with all reasonable loads. Commercial ammo and military ball. No adjustment needed. Read about it on their website. I have one and it works.

Nice looking wood! I haven't got an adjustable gas plug but I seem to remember talk of the Shuster gas plug.

I'm looking for one that is adjustable. At least I think I do. From what I understand, you can dial in tighter groups. It also lets me experiment with a wider range of bullets; I can adjust the amount of gas so that the op rod is not at risk and the action is cycling with an optimal amount of pressure.

Why, why screw with a good thing?

Why, why screw with a good thing? Well, it's really easy to unscrew. The Schuster plug comes factory set to vent most gas so the action will not operate. Directions say to start by closing or screwing in the plug 1/4 turn at a time until the action functions. I installed one in mine and have it set so it functions slower than normal even with mil spec ammo. Theory is that slowing it down protects the operating rod. My gun has been totally reliable after adjusting.

Still have the original plug if I ever want to re-install it.

I got the Schuster. Haven’t used it. I have A box of Remington 150’s through it with no problems.

I can see why. A Garand is a fine rifle. I love to hunt with mine but with the stock gas setup you have to be careful with ammo and at that you're limiting performance. I want to get one of these adjustable gas plugs too. If you're worried about keeping it original just keep the old stock parts in a safe place and if you ever want to put it back in original condition you've got the parts right there. That way you can hand load hotter ammo and different weight bullets without worrying about damaging the op rod.

Thanks all! I'll probably order the Schuster after I dig out from Christmas.

This is the one I'd try. Been wanting to for years but haven't gotten around to it. I'd rather not have to make adjustments. Just screw in and go. They're a good company to deal with too. Just my 2 cents....

I have used the Garandgear plug fairly extensively ( about 5 rifles), and like the concept. Also the fact that you are not tied to one load and have to readjust if you change loads.
The only warning I have is to occasionally clean the chamber in the ported plug, as it will slowly fill with carbon and you lose the pressure reduction, but the same happens with the plugs that work by venting.

And carry the issue plug in the buttstock. My kid's M1 did not cycle150 grain Remington CoreLokts with the non-adjustable plug in place. I still like the idea of not bending an op-rod so the trick plug stays in.

I load H-4895 for mine. Supposed to mimic the Garland load.

+1......... Didn't feel like messing with variables so I just run one IMR-4895 G.I. Equivalent load to keep things as they were meant to be. Use regular 150 gr. FMJ for paper punching and just substitute some Nosler 150 gr. Accubonds for hunting use. Both bullets shoot well and I feel better knowing my load is M-1 compatible without having to adjust things. Guess I just don't trust my op rod to anything but a standard M-1 load.

Update: I finally got the Garand out with some test rounds to see if the Schuster plug was worth it. We're Sneaking InBottom line: It took 6 rounds to get the plug dialed in, going from fully open and closing it a quarter turn per round. I then turned it on my gong at 200 yards and rang it 24 for 24.

Is it better? Or, could you do the same with proper Garand ammo?
