Yes, single-action, no kaboom.
All that happens is there is no gas impulse to push the bolt carrier back to clear the chamber and load the next round. The recoil may push the BCG back a little, but it will not be enough to extract+eject the spent casing and chamber the next one.
This happens when the gas system (aperture, gas block, and/or gas tube) gets clogged with deposits.
Care to share the root of your question?
