View Full Version : Winchester M100 dissasembly problem

September 2, 2006, 12:52 AM
I know this is a Ruger forum, but I would imagine the knowledge I need to tap is here.
I have been working a couple of rifles for a soldier, a Winchester M94 that I fixed and gave back, and a Winchester M100. The M100 has me stumped. I cannot get it to dissasemble because the bolt won't retract. According to the dissasembly instructions in the NRA book I have, the bolt must be retracted in order to separate the action from the stock. I have tried everything and it will not retract. I think it may be something in the trigger assembly, but that is just a guess. The safety doesn't seem to work properly either. It won't switch from safe to fire positions and the trigger feels like the hammer is in the down position. Any ideas?

Do a Google search on "Winchester Model 100" and you should turn up someone with a manual.

Beyond that, I have had a number of guns like that where someone had assembled them wrong, but never a Model 100. The best I can tell you is that if the manual's instructions don't help just keep fiddling with it. Most of a gunsmith's experience in this stuff is simply knowing what not to fiddle and when not to go too far. If you can get the stock off, you might be able to see what is wrong, but that seems to be the problem.

P.S. You must be posting on other sites, as this is not a Ruger forum; it is an everything forum.

There is a thread on Harley Norton's forum that might help.

Yes, I did post on Ruger forum. I was having trouble accessing this site and was getting desparate. I think you guys answered the question though. There have not been too many guns whip my butt, but this one was working overtime on it. :D I will probably be working on it tonight yet. The internet was not too helpful. It kept trying to take me to sights selling books. I did get a parts diagram and instuction for tearing the gun down from a book I have. It didn't have a troubleshooting area though, :eek:

I will let you fellas know how it turns out.

Mission accomplished!!!! You were right, the hammer was in the uncocked position and I took a 16 penny nail, bent it 2/3 of the way back from the tip and pushed the hammer back. I could not get it to fully cock so while holding the rifle between my legs, hammer partway back with the nail, I pulled the bolt back. It road straight back and cocked the hammer just slicker than a whistle. As soon as the bolt went back the action fell out of the stock. Now to clean it and give it back to that Airman.:D :D :D

you got 'er done. But consider for a moment, if the bolt would not open, how could you tell if there was a round in the chamber? Not knowing for sure is there could be a live round in the chamber makes a world of difference on how I would work on a gun. Never just take someone's word.

Here's a tip if something like this comes up again, take a cleaning rod, and gently run it down the barrel until it stops. Mark the rod at the muzzle. Then remove the rod and compare it with the mark at the muzzle. If the rod doesn't go all the way to where you figure the boltface is, you could have a live round in the gun.

I most certainly will do the cleaning rod check on any future endeavors. It is an excellent idea. I was so glad to get that rifle apart. It is so dirty inside that I think the dirt is his extraction problem. Examining the bolt, the extractor looks unworn and crisp. I have a feeling this gun has not been cleaned in a long time, if ever. Thanks for all of your help. This rifle was quickly kicking the hind end.:confused:
