Faxon Firearms ARAK-21 Complete Upper Receiver Review

First Impressions of Faxon Firearms ARAK-21 Complete Upper Receiver

The Faxon Firearms ARAK-21 Complete Upper Receiver promises to be a game-changer for the AR platform, offering a gas piston operating system in a drop-in package. Faxon Firearms aims to deliver improved reliability and compatibility with folding stocks. My initial intrigue stemmed from the promise of reduced recoil and enhanced performance in adverse conditions, things I often encounter during my outdoor excursions.

I was looking for an upper receiver that could handle the demands of both tactical training and extended backcountry use. I’ve always been drawn to piston-driven systems for their cleaner operation and potentially increased reliability, especially when paired with suppressors. Upon unboxing, the ARAK-21 felt solid, with a robust quad rail and an overall impression of quality craftsmanship.

Compared to a standard DI (direct impingement) upper, the ARAK-21 felt noticeably heavier. It had a similar feel to the Adams Arms piston kit I previously used, but the ARAK-21’s monolithic design seemed more robust. I chose this over other piston uppers, like those from PWS (Primary Weapons Systems), because of its self-contained system and purported ease of installation without requiring any modifications to the lower receiver. My first impression was a mix of excitement and slight apprehension due to the weight, hoping the performance would justify the added heft.

Real-World Testing: Putting Faxon Firearms ARAK-21 Complete Upper Receiver to the Test

First Use Experience

My first range trip with the Faxon Firearms ARAK-21 Complete Upper Receiver was at a local outdoor range on a moderately sunny day. The temperature was around 65 degrees Fahrenheit, with a slight breeze. I mounted it on my standard mil-spec AR-15 lower with no modifications. Installation was truly drop-in, as advertised, requiring no special tools.

The ARAK-21 performed admirably, exhibiting consistent cycling and noticeably reduced recoil compared to my DI upper. The adjustable gas system allowed me to fine-tune the performance for various ammunition types. There were no malfunctions during the first 200 rounds; however, the increased weight was noticeable, especially during rapid-fire drills.

Extended Use & Reliability

After several months of regular use, including numerous range sessions and a weekend backcountry camping trip, the Faxon Firearms ARAK-21 Complete Upper Receiver has proven to be a reliable performer. The finish has held up well, showing only minor wear marks on the quad rail from mounting accessories. Cleaning is significantly easier than with a DI system, as the bolt carrier group remains much cleaner.

Maintenance is straightforward; occasional lubrication of the bolt carrier and piston components is all that’s required. Compared to my experience with DI systems, the ARAK-21 requires less frequent and less intensive cleaning. It outperforms my previous DI upper in terms of reliability, especially when using a suppressor. However, the weight remains a constant factor, making it less ideal for long-distance hiking or situations where maneuverability is paramount.
