M1 Garand gas plug issue.

#1 Post by sikacz » Tue Oct 02, 2018 11:56 am

I took my M1 Garand for a second outing at our Texas shoot meet. I had two issues after my first time out. On the first it started to dump, eject all the rounds after a few shots. That was fixed by replacing the clip latch spring. The second issue was that the gas plug would back out enough that the front sight would be loose, wiggle. I thought I had tightened it enough, but apparently not. Thoughts on a fix appreciated.

You using a torque wrench or just tightening by hand to where you think it should be? 15lbs is the standard I believe.

By hand with a gas plug tool as shown in the picture. I'm sure I was over 15lbs. Not sure what I can use to put on my torque wrench to fit the plug. Also the lug tool is no as marr free as advertised. I put some muscle into it last night, but I'm skeptical.

I've always just gone with wrench it on till I'm sure, but as with anything, our versions of that could be very different. Haven't had an issue with mine coming loose. Also not using any grease on the threads or anything.

Point of note- I've also always just used my 1/4" driver to tighten it- Don't have the fancy tool.

Not sure a 1/4" will work on this very well. Is this like yours?

I don't believe I put any grease or oil on it. Can't say that it was degreased very well or not.

Yep, mine looks just like that. Try the 1/4" driver, should slip right in.

You said you didn't use any other tool? How did you restrain the collar during torquing? I'm going to degrease the threads and try with 1/4" and a torque wrench. I think I'll peen the sight groove a bit too. Thanks.

I use a rifle cleaning stand and just hold it by hand around the collar. It's not a ton of torque that I applied, just as much as I could comfortably do and still hold on with my left.

I’m wondering if red loctite (in the blue tube) may work? Or would the heat from the barrel tend to negate its lock-threading effect?

Red loctite is a definite NO GO- that stuff is semi-permanent. Blue perhaps

Ah, gotcha. Looks like I got the red and blue ones mixed up.

My GarandGear ported plug arrived today. The instructions that came in the package said to torque the plug to 10-15 ft-lbs. FWIW
