Eugene Stoner hated the idea. He said if your bolt didn't close, you had not done proper maintenence and your rifle should be cleaned. The Army made him put it on anyway.
Wasn't the M16 pitched to the Army as a weapon that didn't need cleaning?
No, it was pitched as one that needed
less cleaning. And with the IMR powder the test ammo was loaded with, it really did only need a little maintenance now and then. But the Army changed everything to ball powder, which is sooty and filthy, and therein lay the deaths of hundreds of GIs in Vietnam because Ordnance was pissy about the whole thing.
And Stoner was an engineer (and a very good one), but not a soldier. He didn't think "worst case" as a matter of course, the way a soldier needs to. Ideally, the steel-lined, aluminum barrel he designed should have made the gun only 2/3 the weight is is and still have held up, but Ordnance made sure it didn't and multiple-layer barrels don't seem to have been tried ever again.
