What Makes an AR 15 Mil Spec?

How Important are Mil-Spec Parts for the AR-15?

When it comes to the AR-15 community, the term "mil spec" is often used with a sense of reverence and praise. But what does it really mean, and does it truly matter? Let's delve into the meaning of mil spec and its significance in the world of AR-15 rifles.

At its core, "mil spec" refers to the standards set by the U.S. Department of Defense (DOD) for various firearms. It is a shortened form of "military specification," often denoted as MIL-STD. These specifications outline the requirements that firearms, including the AR-15, must meet to be considered suitable for military use. However, in the context of the AR-15, the term "mil spec" is also used to describe custom AR parts that strive to meet the same specifications as those set by the military.

It's important to note that any commercially produced AR-15 rifle is not technically mil spec.

True mil spec firearms are those that meet specific standards mandated by the DOD and are produced under government contract for military use. The technical requirements for the military's version of the AR-15, known as the M16, are outlined in the MIL-SPEC handbook, which provides precise measurements and materials. However, even if a custom AR part matches the specifications outlined in the handbook, it does not automatically make it mil spec. Only parts produced specifically for the U.S. military can truly be considered mil spec. These actual mil spec firearms are rare, expensive, and nearly impossible for civilians to obtain.

The Importance Of Mil Spec

So, does mil spec really matter for the average AR-15 owner? While owning a fully mil spec firearm may not be feasible or necessary, many AR owners appreciate the compatibility and interchangeability of mil spec designs. The AR-15's modular nature allows for easy customization, and with the availability of the MIL-SPEC handbook, it is possible to modify your AR with custom parts that closely adhere to military specifications. Although these aftermarket parts aren't technically mil spec, they can be made to the same standards as those used in the M16. From bolt carrier groups to M4 feed ramps, a wide range of components can be sourced to mimic the mil spec design.

Ultimately, the importance of meeting mil spec specifications in every aspect of your AR-15 comes down to personal preference. As long as you comply with legal regulations, you have the freedom to customize your AR to your liking, whether that means adhering strictly to mil spec or mixing and matching components based on your needs and preferences. Customizing your AR-15 allows you to optimize its performance and ergonomics, enhancing your shooting experience.
