AR-15 A1 vs A2: A Comprehensive Comparison

When it comes to the AR-15 rifle, there are two models that often stand out: the A1 and the A2. Both are popular among shooters for their reliability, accuracy, and versatility. But what sets them apart? Let’s dive into a detailed comparison of the AR-15 A1 and A2 to help you decide which one is right for you.

Design and Construction

The AR-15 A1 and A2 share a similar design philosophy, with the A1 being the older of the two. The A1 features a fixed carry handle, which is a distinctive feature that sets it apart from the A2. The A2, on the other hand, has a collapsible stock and a forward assist, which are not present on the A1.

The A1 is typically made from forged aluminum, which is known for its strength and durability. The A2, however, is often made from billet aluminum, which is even stronger and more resistant to wear. This difference in construction can affect the weight and feel of the rifle, with the A2 generally being lighter and more agile.

Caliber and Ammunition

Both the AR-15 A1 and A2 are available in a variety of calibers, but the most common is 5.56x45mm. This caliber is known for its high velocity and excellent penetration capabilities, making it ideal for both hunting and tactical applications.

While the A1 and A2 can use the same ammunition, there are some differences in magazine compatibility. The A1 typically uses magazines with a 20-round capacity, while the A2 can use magazines with a 30-round capacity. This is due to the forward assist on the A2, which requires a larger magazine to function properly.

Barrel and Muzzle Device

The barrel is one of the most critical components of any rifle, and the AR-15 A1 and A2 have different barrel options. The A1 typically comes with a 20-inch barrel, while the A2 can have a barrel length of 18 inches or 20 inches.

The A1 barrel is often threaded with a 1/2×28 TPI (threads per inch), which allows for the attachment of various muzzle devices, such as flash suppressors, compensators, and suppressors. The A2 barrel, however, is threaded with a 1/2×36 TPI, which is not compatible with some muzzle devices designed for the A1.

Stock and Handguard

The stock and handguard are essential for comfort and control, and the AR-15 A1 and A2 offer different options. The A1 features a fixed carry handle, which provides a solid grip but limits the rifle’s adjustability. The A2, on the other hand, has a collapsible stock, which allows for a more personalized fit and easier transport.

The handguard on the A1 is typically a fixed design, while the A2 offers a variety of handguard options, including the M4 carbine handguard. This allows for better ergonomics and the attachment of accessories, such as lights, lasers, and sights.

Price and Availability

When it comes to price, the AR-15 A1 and A2 can vary significantly. The A1 is often more affordable due to its simpler design and fewer features. The A2, with its collapsible stock and forward assist, tends to be more expensive.

In terms of availability, the A1 is more common, as it has been in production for a longer time. The A2, however, is still widely available and can be found at most firearms retailers.

Conclusion

Choosing between the AR-15 A1 and A2 ultimately depends on your specific needs and preferences. If you’re looking for a more affordable, simpler rifle with a fixed carry handle, the A1 may be the better choice. However, if you want a more versatile, customizable rifle with a collapsible stock and forward assist, the A2 is the way to go.

Remember that both models are reliable and accurate, so the decision should be based on your personal requirements and budget.
