M1 Carbine Durability and Arsenal Rebuild Specs

I have some 1950's documents that indicate M1 Carbines with more than 15,000 rounds through them should be removed from service, and tagged for arsenal rebuild. To me, this seems like a relatively low round count for such action when compared to other military firearms.

There has been recent discussion among M2 Carbine owners that folks are shooting their M2's less often, and it doesn't have anything to do with ammunition cost. They are worried about continued full auto abuse on the receiver and other components.

Obviously, the M1/M2 Carbine is a lightweight weapon, and mechanical longevity may not necessarily have been a consideration in its design. It served our country well for about a quarter century, and its users either loved it, or hated it, with the latter mostly attributing their angst toward decreased stopping power when compared to other weapons, in my discussions with past combat users.

So, has anyone among us fired more than 15,000 rounds through their M1/M2 Carbine(s)? Has anyone observed any significant wear or abuse of concern after that many rounds were fired? I've only put about 500 rounds through my 3 M1 Carbines over the years, so I can't say myself. If I shoot a 15 round magazine through one of mine, I'm usually done, and on to the next gun. Does anyone consider the weapon "fragile?"

Any input on the subject is appreciated.

Thanks!
