Universal M1 Carbines came in three basic Types.
Type 1 was USGI and all parts interchanged with regular Government Issue Carbines. This is because they were made from parts purchased from the Government after World War II.
The Type 2 M1 Carbines were made from a mix of USGI parts and parts manufactured for the rifles. This is because the manufacturer was running out of the leftover USGI parts. So some parts you can find others wont fit the rifles.
The Type 3 like you have were a different style of rifle all together. Unlike the original USGI Carbines that had a single recoil spring, they used a Two Spring Recoil System. This is the carbine that most people like myself have had the problems with.
You may have gotten lucky and purchased a good rifle. It is very hard to get parts for the Type 3 because they used parts that no other M1 Carbine has.
My experience with a Type 3 Universal M1 Carbine is that it would, as Chris said, fire out of battery. In fact the Op rod would disconnect from the bolt when you fired it. It also would blow the metal ventilated handgaurd off. It would fail to fire (FTF) and fail to extract (FTE) constantly. It was the most frustrating rifle to shoot. I was constantly putting it back together.
Its actually the only rifle I ever got rid of.
That is only my experence with the Universal Carbine. Others on this forum have some and have no problems with them at all.
Good luck with yours.
It is foolish and wrong to mourn the men who died. Rather we should thank God that such men lived.
