Mil-Spec is:
Mil-Spec is military specifications that the suppliers agree to manufacture the products they are going to sell to the military.
These includes material, process, dimensional and quality standard specifications.
Materials like 4150 alloy steel for the barrel instead of 4140 alloy. Finish materials like parkerizing and anodizing are specified of which suppliers are qualified. Rockwell hardness and finish smoothness values.
Process in machining, forging, heat treating, drilling, cutting, fasteners, molding and finish.
Dimensional examples are like the 1/7 twist rate, M4 feedramps dimensions and on carbines, buffer tube diameter which commercial brands stocks will not fit it.
Quality standards like 100% inspection not by random or batches and military suppliers have to perform ISO 9001-2000 quality standards. The ISO standards is at least only one third of the normal engineering drawing tolerance or better.
You won't feel any of that when shooting a Mil-Spec and a commercial brands but the quality is built in. Most civilian customers won't even wear out both Mil-Spec and commercial brands in their lifetime.
Even foreign manufacturers like in China makes Mil-Spec and commercial brands of AK-47. The Mil-Spec Poly Technologies brand uses chrome bores, gas piston and BCG. Heat treats critical parts and maintains smaller dimensional variation. The commercial brand Norinco don't have those features in their rifles.
It's up to the individual buyers what rifle they want and buy what they want, to each his own.
