How Long Is an AR-15? Understanding AR-15 Rifle Dimensions

The length of an AR-15 isn't a single, straightforward answer. Unlike many firearms with fixed dimensions, the AR-15 platform's length is highly customizable and varies significantly depending on several factors. This guide will break down the influencing elements and give you a better understanding of the typical AR-15 length range.

Factors Affecting AR-15 Length

Several key components directly impact an AR-15's overall length:

  • Barrel Length: This is the most significant factor. AR-15 barrels commonly range from 7.5 inches to 20 inches, and even longer in some specialized builds. Shorter barrels mean a more compact rifle, while longer barrels often provide increased accuracy and velocity.

  • Handguard/Rail System: This component protects the barrel and provides mounting points for accessories. Different handguard lengths dramatically affect the overall rifle length. Some are as short as 7 inches, while others extend to 15 inches or more.

  • Stock: The stock's length contributes to the rifle's overall length and adjustability. Collapsible stocks allow for significant length adjustments to fit different shooters, while fixed stocks have a set length. Different stock types also contribute to overall length.

  • Brace (vs. Stock): The use of a brace instead of a traditional stock can slightly alter the overall length. Braces are generally shorter and offer more compact configurations. However, legal regulations surrounding braces vary and should be carefully considered.

Typical AR-15 Length Ranges

Considering the variability in components, here's a general overview:

  • Short-barreled AR-15s (SBRs): These rifles, with barrel lengths under 16 inches, are generally shorter and more compact, often falling in the 26-30 inch range. Importantly, owning an SBR typically requires special licensing and registration.

  • Standard AR-15s: With typical 16-20 inch barrels, these rifles usually range from 34 to 40 inches in overall length. This is the most common length range for AR-15s.

  • Longer-barreled AR-15s: Rifles with longer barrels (over 20 inches) can extend beyond 40 inches in length. These are less common but are often preferred for long-range shooting.

Measuring Your AR-15

The most accurate way to determine your AR-15's length is to measure it directly. Use a tape measure and measure from the end of the muzzle to the end of the stock when fully extended.

Conclusion

The length of an AR-15 is highly variable and depends on the chosen components. Understanding the factors that affect length is crucial for selecting a rifle that best suits your needs and intended use. Remember to always check and adhere to all local, state, and federal laws and regulations regarding firearm ownership and modifications.
