What Type Of Ar-15 Does The Military Use? A Comprehensive Guide

When it comes to firearms, especially in the realm of military hardware, the AR-15 style of rifle garners a lot of attention. Many enthusiasts and novices alike often find themselves asking, “What type of AR-15 does the military use?” Although the AR-15 is frequently associated with civilian ownership, it's essential to understand the distinctions between the civilian variants and the military specifications.

Understanding the AR-15 and Military Variants

The AR-15 is a lightweight, air-cooled, gas-operated, magazine-fed semi-automatic rifle designed by Eugene Stoner in the late 1950s. Initially produced by ArmaLite, the design has evolved, leading to various adaptations and models. While many may assume that the military uses AR-15s, it is more accurate to say that they use a variant known as the M16 or M4 Carbine, both of which are derivatives of the original AR-15 design.

The M16 and M4: Military’s Chosen Models

1. M16 Rifle

   • The M16 has been the standard-issue rifle for the U.S. military since the Vietnam War. Over the years, several models have been developed, including the M16A1, M16A2, M16A3, and M16A4.
   • Specifications:
     • Caliber: 5.56×45mm NATO
     • Weight: Approximately 8.79 lbs (M16A4)
     • Rate of Fire: Semi-automatic and fully automatic modes in some variants.
   • The M16 was designed for both accuracy and range, with a longer barrel that contributes to enhanced ballistic performance.

2. M4 Carbine

   • The M4 is a shorter, more compact version of the M16, designed for greater maneuverability in close quarters. It has become the primary infantry weapon in modern military operations.
   • Specifications:
     • Caliber: 5.56×45mm NATO
     • Weight: Approximately 6.4 lbs
     • Rate of Fire: Semi-automatic, three-round burst, or fully automatic.
   • The M4 also features a collapsible stock and Picatinny rails for mounting accessories, making it highly adaptable.

Why the Military Prefers These Models

The choice of the M16 and M4 over civilian AR-15s boils down to several factors, including:

Tips for Choosing Your AR-15
