Faxon Firearms AR15 Upper Receiver Groups 1 Review

Let’s Dive into Faxon Firearms AR15 Upper Receiver Groups 1

The Faxon Firearms AR15 Upper Receiver Groups 1, specifically the ARAK-21, promises a departure from the standard AR-15 upper receiver. Designed by Faxon Firearms, this upper receiver group aims to offer enhanced modularity and ambidextrous controls, all while maintaining AR-15 compatibility. This unique design caught my eye as I have been searching for an AR platform that allowed for quick caliber changes and improved left-handed ergonomics without requiring a complete rifle build.

I’ve always been on the lookout for ways to improve the AR platform, especially for left-handed shooters like myself. Frustration with brass deflecting into my face during training scenarios led me to seek an ambidextrous, forward-ejecting upper receiver. The Faxon Firearms ARAK-21 seemed like the perfect solution.

My initial reaction upon unboxing was one of cautious optimism. The machining appeared clean, and the aluminum felt lightweight yet sturdy. It was evident Faxon Firearms put significant effort into the ARAK-21’s design.

Compared to a standard AR-15 upper from Aero Precision and a side-charging upper from Gibbz Arms, the ARAK-21’s monolithic quad-rail design immediately stood out. While the Aero Precision offered a reliable baseline and the Gibbz Arms provided improved charging, the ARAK-21 offered ambi-charging and promised easier barrel swaps. I hoped its innovative design would provide superior versatility, justifying its higher price point. I was excited by its potential, but also wary of potential drawbacks associated with deviating from the AR-15’s proven design.

Real-World Testing: Putting Faxon Firearms AR15 Upper Receiver Groups 1 to the Test

First Use Experience

I first tested the Faxon Firearms AR15 Upper Receiver Groups 1 at my local outdoor range, primarily focusing on function and accuracy at 50 and 100 yards. I tested it in relatively dry conditions with temperatures around 70 degrees Fahrenheit. The ambidextrous charging handle was immediately comfortable to use, and the recoil impulse felt different from a standard direct impingement AR-15.

The unique recoil system seemed to reduce muzzle rise compared to my other ARs. There was a slight learning curve involved in understanding the barrel swap process, but it quickly became intuitive after a few repetitions.

Extended Use & Reliability

After several months of use, with approximately 1,500 rounds fired, the Faxon Firearms AR15 Upper Receiver Groups 1 has held up surprisingly well. I’ve noticed only minor wear marks on the bolt carrier contact points. Cleaning is relatively straightforward, although accessing some areas within the quad rail requires a bit more effort than with a standard handguard.

Compared to my standard AR-15, the ARAK-21 requires slightly more frequent lubrication due to its unique operating system. However, its overall reliability has been comparable. It has outperformed other piston-driven AR uppers I’ve tested in terms of smoothness and felt recoil.

• The bolt design incorporates an eight-lug bolt with an involute profile. This provides robust lockup and reliable extraction.

Performance & Functionality

The Faxon Firearms AR15 Upper Receiver Groups 1 excels in offering a versatile and ambidextrous AR-15 platform. Its modular barrel system allows for quick caliber changes, and the non-reciprocating charging handle significantly improves ergonomics. Accuracy is comparable to a standard AR-15, and the modified recoil system offers a noticeable reduction in muzzle rise.

The ARAK-21’s primary weakness lies in its proprietary design. This means that some standard AR-15 parts are not compatible, potentially limiting customization options. The overall performance met my expectations, providing a reliable and adaptable upper receiver group.

Design & Ergonomics

The Faxon Firearms AR15 Upper Receiver Groups 1 boasts a robust and well-thought-out design. Its all-aluminum construction keeps the weight manageable, while the quad rail provides ample space for accessories. The ambidextrous charging handle is well-positioned and easy to manipulate from either side.

The ARAK-21’s slightly bulkier profile compared to a standard AR upper is a minor drawback. However, the improved ergonomics and modularity more than compensate for this.

Durability & Maintenance

The Faxon Firearms AR15 Upper Receiver Groups 1, constructed from 6061-T6 aluminum, is built to last. The anodized finish provides excellent resistance to corrosion and wear. With proper maintenance and lubrication, it should provide years of reliable service.

Disassembly and cleaning are relatively straightforward, but require familiarity with the ARAK-21’s unique operating system. Specific tools may be required for certain maintenance tasks.

Accessories and Customization Options

The Faxon Firearms AR15 Upper Receiver Groups 1 is compatible with a wide range of AR-15 accessories, including optics, lights, and foregrips. Its quad rail provides ample space for mounting these accessories. The key customization option is the ability to swap barrels for different calibers.

The ARAK-21 is not compatible with all aftermarket AR-15 parts due to its proprietary design. Be sure to research compatibility before purchasing any aftermarket components.
