Barrel Length

One of the main differences between a 16 inch AR-15 and a 20 inch AR-15 is the barrel length. The 16 inch AR-15 has a shorter barrel, which makes it more compact and maneuverable. This can be advantageous in close quarters or when carrying the rifle for extended periods of time. On the other hand, the 20 inch AR-15 has a longer barrel, which can provide better accuracy and velocity for long-range shooting.

Weight

Another key difference between the two rifles is their weight. The 16 inch AR-15 is typically lighter than the 20 inch AR-15 due to its shorter barrel length. This can make the 16 inch AR-15 easier to carry and handle for extended periods of time. However, some shooters may prefer the added weight of the 20 inch AR-15 for increased stability and reduced recoil.

Accuracy

When it comes to accuracy, the 20 inch AR-15 has the edge over the 16 inch AR-15. The longer barrel of the 20 inch AR-15 provides a longer sight radius, which can help improve accuracy at longer distances. Additionally, the longer barrel can also help to stabilize the bullet as it travels down the barrel, resulting in better precision. However, the 16 inch AR-15 is still capable of delivering accurate shots, especially at shorter ranges.

Velocity

Velocity is another important factor to consider when comparing the two rifles. The longer barrel of the 20 inch AR-15 allows for a longer dwell time, which can help increase the velocity of the bullet as it exits the barrel. This can result in a flatter trajectory and better terminal ballistics at longer distances. On the other hand, the 16 inch AR-15 may have slightly lower velocity due to its shorter barrel length, but it is still capable of delivering sufficient velocity for most shooting scenarios.

Maneuverability

When it comes to maneuverability, the 16 inch AR-15 has the advantage over the 20 inch AR-15. The shorter barrel length of the 16 inch AR-15 makes it easier to handle in tight spaces and allows for quicker target acquisition. This can be beneficial in tactical situations where speed and agility are crucial. However, the longer barrel of the 20 inch AR-15 may provide better stability and control for more precise shooting, especially at longer ranges.

Overall Performance

Ultimately, the choice between a 16 inch AR-15 and a 20 inch AR-15 will depend on the shooter's preferences and intended use. The 16 inch AR-15 is a versatile option that excels in close to mid-range shooting scenarios, while the 20 inch AR-15 is better suited for long-range shooting and precision shooting competitions. Both rifles have their own strengths and weaknesses, so it's important to consider factors such as barrel length, weight, accuracy, velocity, and maneuverability when making a decision.
