On the AR15/ M16, the spring is retained by the buffer. The buffer is retained by a pin located at the lower outer edge of the extension tube.

What would happen if you fired your ar15 without the buffer inside?

The bolt carrier would not return, another round would be chambered, and you'd likely have to replace a bolt carrier, buffer tube, buttstock (if using a fixed buttstock), and buffer spring (if the spring was in the extension tube). You could also cause injury to yourself if the bolt carrier ended up going through the back of the extension tube.
