10 Best AR-15 Triggers: Drop-In and Mil-Spec
Just a PSA.
The fact is that Mil-Spec has a very precise meaning.
According to a Government Accounting Office (GAO) report, “In general, ‘military specifications’ describe the physical and / or operational characteristics of a product and ‘military standards’ detail the processes and materials to be used to make the product.”
Mil-Spec, then, is related to Mil-Std, which stands for “military standard.” Together they comprise the specifications and standards for making a given product that the U.S. Department of Defense (DoD) has issued as a major part of DoD’s Standardization Program, the goal of which is to ensure that products designed for military use meet the necessary requirements with regard to quality, durability, ruggedness, commonality, inter- changeability, total cost of ownership, logistics and other military and defense-related objectives.
In the case of an M16 rifle or carbine, the military specification might require a weapon’s bolt ( or trigger group) to be made out of a certain type and grade of steel and for it to be made via a specific manufacturing protocol, while the military standard might outline the specific inspection and testing protocols for and relating to that part.
“Commercial black rifles or aftermarket parts are not considered Mil-Spec because there is no U.S. government verification to assure that their performance, endurance, accuracy, interchangeability and reliability meet all of the detailed and exacting military standards and specifications imposed by the United States Armed Forces.”
Just so we’re crystal-clear on this important point: no commercial AR-15 carbine or rifle, components are not nor ever will be, Mil-Spec. If the government is not testing the gun, by definition, it is not Mil-Spec. “Mil-Spec commercial” is an oxymoron.
Don't be sucked in by marketing hype.
