You may have installed the fork on the op rod thingy upside down.

The trigger guard should close with little more than thumb pressure.
Jump on youtube and look for an assembly video to make sure everything is correct. |

The trigger guard should fit very tight on to the stock. It's okay to force it. When they were originally built, the builders used a mallet to close the trigger guard.

Tight fit is good for accuracy, so I've been told. Protect the rear sight and give the trigger guard a good whack with the palm of your hand or a plastic mallet.

If it isn't properly aligned, the trigger group won't go in.

There are a number of threads on this around the net, mine was the same way when I got it earlier this month.
The gist of things I read was that the wood is new and not yet compressed, tight lockup is a good thing, and they say that when originally made that the armorers used a wooden mallet to smack these closed. and they weren't exactly gentle about it. I didn't have a wooden mallet, but I did have a good-sized C clamp. I put a rag on the rear of the receiver on top, and covered the forward part of the trigger guard, put the clamp on so that when tightening, it pulls the trigger guard to the rear and up. It almost seamed too easy as I tightened up on the clamp, it just smoothly pulled back and down till it locked, but I sure as hell couldn't get it to go with just my hand. They say that over time the wood will compress a little bit and it'll get better. |

The "lock up" is an important aspect of accuracy in an M1
Double check your assembly and if everything is correct go ahead and force the trigger guard down. If you have to jump on it, something ain't right. But a fair amount of pressure on a new stock is normal. The lock up squeezes the stock between the receiver and trigger group. In fact I store my M1s with the trigger group unlocked so the stock doesn't compress over time. |

It is optimal to have a tight lockup and have to use some force. The armories used to have to give a good whack with a mallet to lock the trigger group. Ober time the wood will compress and this task will become easier. |

OK, I got it on. A mallet was the key. I can't say I love that, but I guess it's better to have things a bit tight than loose.
Thanks GD. You guys are awesome. |

I also have a relatively new Special Grade.
It has been taken apart only a couple times, and is definitely tougher to reinstall the trigger group than some of the older ones I've dabbled with. As was posted earlier, I suspect it's just a fitting issue and that the wood will eventually conform slightly to make it easier. |

Make sure the lugs on the housing have a bit of lube and that the barreled action fits down in the stock correctly. Then get your rubber mallet (Harbor Freight sells one cheap), turn the rifle over (make sure the rear sight is all the way down), and give it a rap. Viola! |

That will be what I try next. It just makes me nervous doing that kind of thing to a new gun. I checked everything ant it's all put together correctly and the trigger guard is aligned properly. I'll go get my mallet... Quote HistoryQuoted:

It's rebuilt with new and/or old and reused stuff. Mallet is the key as you found. |

By all means, make certain to grease the lugs on the Trigger group housing, and the fork that mates with them. Worn lugs/fork are often seem, and lessen accuracy considerably due to loose lock-up. |

I just got my special grade a week ago. Beautiful tiger striped stock that I'm in the process of using pure tung oil.

I'm not sure whether it's Fred Mertz or Alfred Hitchcock wielding that mallet.

I had the same problem.
Yesterday. Solved by whacking the trigger guard closed with more force. |
