Just because something is stated as being 'mil-spec,' doesn't necessarily mean it adheres to the exact military specification for that item. And even though a manufacturer states it's product has been HPT and/or MPT, it doesn't necessarily mean that those proceedures were carried out in accordance with a military standard.
I understand what the military specifications are and why they are in place. I also feel the term 'mil-spec' is used quite loosely in the consumer market. 'Mil-spec' in that the bolt has been properly manufacturer, tested, but mysteriously not marked? Or 'mil-spec' in that it was made to a standard dimension and will work with 'any mil-spec' carrier?
