    Hey guys. New to the M1 Garand scene and still in a learning stage. Don't know much about them but own one. I took it to the range the other day to get to know the rifle better. My biggest issues I was running into was the weapon not cycling any rounds. It would fire but not cycle. I also had a couple ftf's. I know some issue was not all grease points were lubricated. Any suggestions or help would be much appreciated!

    Does it have an adjustable gas plug?
    Do you shoot factory, commercial .30-06?
    Have you checked the op rod to see if it's bent?

    Hopefully, one of our resident M1 experts will chime in. I would first check the gas plug to see if it is screwed in tight. If so then I would field strip the rifle and look for anything obvious. Myriad of things that could cause a fail to cycle. Things as simple as a gas plug not tight allowing too much gas to escape.

    Remember, M1's need loads that approximate the pressures of ball ammo. That pressure is lower than most commercial ammo.

    First, field strip and clean the rifle muzzle to butt plate. See fi that helps or helps you find something that doesn't look correct.

    PM Orlando. Bill is a great guy and more than willing to help a newbie out with his rifle. Lord knows he has helped me many times.

    Need more info as to exactly what is going on. Does it fire the first round and just not pick up the next? Describe the issue in detail
    What ammo are you using?
    What is stamped on the enbloc?
    Does the issue happen with different enblocs?

    Before doing anything else tear down rifle COMPLETLY , cleam and properly GREASE the rifle. While you have the rifle aparts, check the op rod spring . It should measure 20 1/4 to 19 inches long with no kinks, bends or flat spots. If it is out of spec replace it with one for Orion 7 or GarandGear
    As already stated make sure gas screw is tight, look at the back side of it, check for cracks

    That's my suggestion too - strip it, clean it, grease it (Google M1 Garand grease points), then think about an Orion 7 spring kit. That kit can't be beat and is a cheap remedy for many problems.

    The possibility exists that the gas cylinder may be worn out of spec, or even the piston (less likely). My M1 had a worn-out cylinder. There's a vendor called The Garand Guy that sells dandy kits with a rebuilt cylinder, front sight, gas plug, and nut, all refinished. Looks great, works even better. My M1 shoots wonderfully now!

    I hope the OP returns and responds. I learn a lot from threads like this!

    Many things can cause the OP's issue. You need to rule out the simple most most obvious first
    Properly greased
    Op Rod spring in spec
    bad enblocs
    After these all check out then we can go from there , otherwise you can be going in circles

    Gas port could be plugged with crud too.
  9. Gas cylinder could be misaligned with gas port in barrel. Won't work without gas.

    The op rod spring may be installed backwards. One end is smaller internally and externally than the other. The small end needs to be back at the receiver. If spring is reversed it will bind under the barrel and shut everything down.

    Using any ammo besides M2 Ball is the most likely problem.

    Repair or replace the op rod (if that is the problem) then replace the stock gas plug with this (it only cost about $40 and allows you to shoot almost any commercial ammo -I know this because I have one and use off the shelf ammo) Ported Gas Plug.

    Have you tried the tilt test?
    I reload for mine so I bought a adjustable gas plug.

    I bought a sks many years ago and it wouldn't cycle. A quick test I did was wrap duck tape around gas tube and test fired it in my basement. Fire shot out around gas tube, blowing tape out where gas was leaking. I replaced gas tube with no further problems. Just my 2 cents, sounds like it might be leaking gas some where.
  15. Usually but not always, on a Garand, its the op rod spring. Just like Orlando said.

  17. I have a M1 Garand also. I purchased it at a flee Market yrs. ago and it had the same problem. I had a gun smith look at it and he put a new slide on it. It help a lot. But once and while it will misfire a round. It can be a lot of different things that would cause it. Cheap Ammo is a big one. I also think its the Guns nature to do that. I've noticed in a lot of movies, like for instance the movie "Saving Private Ryan" there were a lot of misfires in M1 Garands in that movie. I'm sure because I own 1, is why I even noticed it. Good Luck, be Happy U have a piece of History.
  18. While in the 101st airborne div, I was in charge of my unit's history records. We had an interview written about an encounter during WWII where the soldiers had shot their weapons a lot, and it was locking up to the point they had to coat them in oil and manually work the mechanism. So yeah, apparently a common issue even in fighting.

  19. This is sounding like there is rust up inside the gas cylinder. Try this, place it muzzle down on a paper towel folded into like a 3" square and put about 10 drops of 0W20 Mobil 1 synthetic motor oil on the bottom of the op rod and let it slide down the op up into the gas cylinder. First do it with the rod locked to the rear and then let the bolt go forward and do it again.

    Do you know how to disassemble it?
