What is wrong when a Carbine doubles?

[JBS]

Bill Ricca will know the answer to that question

After it doubles, does it load a live round with a tripped hammer? Causing you to eject live round and reset hammer?

Hi JBS,

seems that the sear is the problem. What do you think, is adding material by laser welding worth an try? I´m looking for an new one and hope that i will find one over here.

Herr Gunner,

Ulrich, gebst Du mir Deine Adresse wieder. Ich habe ein anderes Sear brauche ich nicht. Ich werde ihn zu euch senden.

Yes it loads the next round and you can fire again.

Are there any restrictions in sending one from the US to Germany? It's only a $10-$15 part plus shipping for an Inland, more if you need a harder to find maker like Rock-Ola or IP/S'G'.

As far as i know are only parts like the Barrel or the complete trigger group and such parts not allowed to ship. $10-$15 is cheap and it is an Inland part.

The primary cause of doubling in the M1 Rifle is operator induced. In virtually all cases the rifle only doubles, and never more than that. The trigger is pulled very slowly, and the rifle held lightly against the shoulder; many times from a benchrest. When the rifle recoils it hits the shoulder and bounces back forward where the trigger finger is still around the trigger, firing it.
If it were the sear, would it stop at only one extra shot, or would it fire multiple shots?

I had one that would do about 8 to 15. As long as you held the trigger back. Let off trigger and it would load a live round with a dead hammer.
From what I have read this did take place at times during production.
It was the sear spring..New spring and no problems...

Hi, it stops after one extra round( that costs me a crade of beer yesterday because i hit the light at 30meters). I´m shooting of hand from prone position and think that i hold it tight enough but i´ll have a look at the next time if it is really tight enough.

...worth an try! Thank you.

8 to 15 times is definitely mechanical problems. Match tuned semi-auto rifles fired from the bench are bad about doubling for the reason mentioned above.

I had the same problem last summer. I had just changed the barrel and put it back togeather. Loaded three rounds, when I pulled the trigger. It fired two rounds. The funny thing is it had never done it before. I loaded three more rounds, it done it again. I changed the sear, that fixed it. My M1A did the same thing a few years ago. A new hammer stopped that problem.
