What is the AR-57?

The AR-57 is a semi-automatic carbine designed and produced by American Rifle Company, also known as AR57. It is a unique firearm that utilizes the upper and lower receiver structures of the AR-15 rifle, but with a twist. The AR-57 is designed to use the 5.7x28mm ammunition, originally developed for the FN P90 personal defense weapon.

Design and Features

The AR-57 is a fascinating piece of engineering. It takes the traditional AR-15 lower receiver and pairs it with a custom upper receiver designed for the 5.7x28mm cartridge. This allows the AR-57 to use the same 50-round magazines as the P90, which is quite impressive. The gun features a free-floating chamber and a traditional AR-15 style ejection port, which is located at the bottom of the receiver.

One of the most notable features of the AR-57 is its use of the FN P90 magazines. This is a significant departure from the typical AR-15, which uses magazines designed for the 5.56x45mm NATO cartridge. The use of the P90 magazines gives the AR-57 a unique look and feel, and it also allows for a higher capacity than most AR-15s.

Performance and Accuracy

The AR-57 is known for its excellent accuracy and reliability. The 5.7x28mm cartridge is a high-velocity, low-recoil round that is designed for close-range combat. This makes the AR-57 an ideal choice for CQB (close quarters battle) scenarios. The gun’s lightweight design and compact size also make it highly maneuverable, which is another advantage in CQB situations.

One of the key benefits of the 5.7x28mm cartridge is its high velocity. The bullet travels at a much faster speed than the 5.56x45mm NATO cartridge, which means it can penetrate barriers more easily. This makes the AR-57 a versatile firearm that can be used in a variety of different situations.

Applications and Market

The AR-57 was initially designed for civilian use, but it has also found its way into the hands of law enforcement and military personnel. Its unique design and capabilities make it an attractive option for those who need a lightweight, high-performance firearm for close-range combat.

However, the AR-57 is not widely available on the civilian market. Its price is quite high, and it is not as widely distributed as other firearms. This is likely due to its specialized design and limited production.

Comparison with Other Firearms

When comparing the AR-57 to other firearms, it stands out for its unique design and capabilities. While the AR-15 is a popular choice for civilian shooters, the AR-57 offers something different. Its use of the 5.7x28mm cartridge and its ability to use P90 magazines set it apart from other firearms.

One of the main advantages of the AR-57 is its high capacity. The use of P90 magazines allows for a higher round count than most AR-15s, which can be a significant advantage in a high-intensity combat situation.

Conclusion

The AR-57 is a unique and fascinating firearm that offers a different approach to the AR-15 platform. Its use of the 5.7x28mm cartridge and its ability to use P90 magazines make it an attractive option for those who need a high-performance firearm for close-range combat. While it may not be widely available, the AR-57 is a testament to the ingenuity and creativity of modern firearm design.
