Quality Hardware - bolt not closing

[gunsmith II]

Hello, the post about my Quality Hardward M-1 Carbine Serial # 4.6 M, failing to close completely with a shell in the chamber vanished into cyberspace.

There was some advice provided in responses but they disappeared before I could reference them. I would appreciate if those who offered direction would be kind enough to recite their thoughts.

The problem is probably that the extractor is not snapping over the rim. It could be weak recoil spring, frozen ejector protruding and not retracting, frozen firing pin not retracting (unlikely), or frozen extractor jammed closed. Disassemble the weapon and check firing pin, ejector and extractor. If the all move freely, try disassembling the bolt and see if the stripped bolt will close on the chamber with a round in it. If all of the above seem normal it may be a weak recoil spring. Your recoil spring should measure close to 10 1/4".

Let me know what you get.

I had this problem on two carbines years ago. One had a weak recoil spring (9 1/4 inch) and one had a gunked up ejector or extractor (I forget which).

The brass case could be a little long. Probably wouldn't happen with military or commercial ammo but could easily happen with reloaded ammo.

Ha, I didn't even consider handloads!

But from the picture I have to assume the rifle in question is firing Remington factory SPs ?

My post suggests you check the extractor plunger and make sure it is not broken and wedged between the extractor and the bolt. This will cause the extractor to not be able to snap over the rim of the shell.

I believe you are on the correct path as all ammo being used in the Carbine is new, ( see earlier jpegs).

The latest jpeg illustrates the current condition of the extractor.

Will this require a "bolt tool" ?

It won't "require" a bolt tool but using one will go a long way toward preserving your sanity.....

on a corresponding shelf in the extractor. As Bill has suggested, the plunger may be turned or disfigured and not be resting where it is supposed to be. It is not uncommon to see it assembled incorrectly and you may need to dress the shelf and plunger with a small file to get it right. It looks like the extractor is being pushed far too much and of course will absolutely refuse to jump onto the cartridge rim if too much pressure is applied via the plunger. I'd sure take it apart and clean out the crud, that in itself may cure your issue.

Excellent suggestion

I have a lot of respect for a soldier in the field trying to fix an extractor on a winter day in Europe with his hands numbed from the cold. After several days of attempting, becoming , walking away from the bench only to return later to try again, the "bolt " now has a working extractor.

Question, did soldiers and officers carry a "bolt tool " with them in the field or just acquire another weapon?
