Default How many rounds can you expect out of a receiver, barrel and parts

I was curious does anyone know the most rounds shot out of a carbine, barrel and all parts thats been documented

5000 rounds ?
10000?

I am figuring a receiver can handle unlimited ?
Curious how many rounds would have been put through a rifle before a barrel would be changed out

I was just curious how many rounds these rifles can handle in general

Im sure this question has been asked but i cant find any info on it.
Please, im seeking honest answers
Thanks

Not using a high power rifle round, and corrosive ammo never used in a carbine barrel, I can't see less than 10,000 rounds having any significant wear to the barrel, and maybe a lot more. Now perhaps an M2 that saw lots of heated fa use
And most of the carbines I've seen, all produced during WWII time frame, still have their original barrels on em.

Most parts have have a very long life. The ones most prone to breakage are the extractor and bolt, which can happen at anytime. Springs, especially the slide spring weaken over time and usage but generally do not break. The slide lugs do wear over time to the point where the slide will jump off the bolt lug. Since we don't know how many rounds any one part may have seen the best thing is to inspect for wear periodically and replace when necessary. Eddie

Poor cleaning technique and steel rods have probably worn out or damaged more barrels than shooting ever will.

I would think tens of thousands of rounds would be the life of a barrel; of course before you can answer your question, one would have to define what constitutes a
shot out or worn out barrel! Performance or measurement by gage?

The military used one test to 15,000 rounds for carbines to be sure of durability. Some would make it and some would not.

I read somewhere that the barrel guage decreases .05 for every 500 rds shot of carbine ammo.
That doesnt seem very many rds.
So mine guages at .15
New barrel guages at .05? An old marine told me this but not sure.
Is this information accurate?

From my experience a carbine barrel will be good for thousands of rounds

Have a rebuilt Rockola with a 10/49 dated SA barrel I bought many years ago that was new from rebuild. I paid $495.00 for it and my shooting buddies ragged me good for paying so much for an M1 carbine. But it was new.
I shot it for years in local CMP club monthly matches and put many thousand(s) of rounds through it.

Measuring the muzzle today a minus .3005 gauge pin will pass through. A minus .3010 gauge pin will not enter the muzzle.

I used a bore snake pull through after each match. Field stripped it twice a year and carefully cleaned the bore with a rod and brush.

While I occasionally shot other carbines during those years the Rockola was my go to gun. I always handled it with care.

The life expectancy of the Carbine & M1 Rifle have outlasted any WWII military expectations. They never made these weapons to last , only to serve a requirement.

I find it amazing how long these weapons have lasted. It is a reminder how great
our industry was in WWII. Long before CNC machining !!!

Spare parts fit.....what quality control was in place !!!

You will never be able to afford the ammo to wear out a USGI carbine...
