Bushmaster A1 Stripped Upper Receiver Review

First Impressions of Bushmaster A1 Stripped Upper Receiver

The Bushmaster A1 Stripped Upper Receiver represents a nostalgic trip for many AR-15 enthusiasts, myself included. This upper receiver harkens back to the classic A1 design, a staple of the Vietnam era and beyond. Bushmaster, once a prominent name in the AR-15 market, brings this piece to life, promising a clone-correct option for retro builds. This upper is intended for those seeking to replicate the look and feel of the original AR-15/M16 rifles.

I have been piecing together a retro AR-15 build for some time, aiming for an authentic representation of the rifles I saw in historical documentaries. The biggest challenge has been sourcing correct parts, particularly the upper receiver, without resorting to exorbitantly priced vintage components. The allure of a “new-old-stock” feel at a reasonable price drew me to the Bushmaster A1 Stripped Upper Receiver.

Upon receiving the upper, the initial impression was positive. The forging appeared clean, and the lines of the A1 carry handle were properly contoured. Holding it in my hands, the weight felt right, and the 7075 T6 aluminum gave a sense of robustness. However, a closer inspection revealed a concerning issue: the color.

Compared to other grey anodized AR parts I own from companies like Brownells and Aero Precision, the Bushmaster upper leaned heavily towards a bluish-grey hue, almost like a parkerized finish gone wrong. This immediately raised concerns about matching it to my lower receiver, a critical aspect of achieving the desired aesthetic. The color discrepancy was significant enough to cause immediate disappointment.

The Bushmaster A1 Stripped Upper Receiver aims to replicate the look and feel of original AR-15 rifles, but the color issue casts a shadow on the overall value. Competitors such as Brownells offer similar A1-style uppers, albeit at a slightly higher price, but they are known for better color consistency. Also, other companies such as Palmetto State Armory offer similar options at a lower price point, though their color accuracy can be inconsistent. Ultimately, the Bushmaster A1 Stripped Upper Receiver promised an affordable pathway to a retro build but fell short in a critical visual detail.

Real-World Testing: Putting Bushmaster A1 Stripped Upper Receiver to the Test

First Use Experience

I decided to test the Bushmaster A1 Stripped Upper Receiver despite my color concerns, hoping that its functionality would compensate for its aesthetic shortcomings. I mounted it onto my lower receiver, installed a bolt carrier group, charging handle, and A1-style handguards. I then headed to my local shooting range for a functionality test.

The rifle functioned flawlessly during the initial range session. The Bushmaster A1 Stripped Upper Receiver paired seamlessly with my existing components, and the rifle cycled smoothly. However, the color clash between the upper and lower was even more pronounced under the bright sunlight, further highlighting the aesthetic issue.

Extended Use & Reliability

After several weeks and approximately 500 rounds, the Bushmaster A1 Stripped Upper Receiver continued to perform reliably. There were no malfunctions or failures of any kind. The finish, despite its color, proved to be relatively durable, showing minimal signs of wear from handling and use.

Cleaning and maintenance were straightforward, as with any AR-15 upper receiver. Standard cleaning solvents and lubricants were sufficient to keep the Bushmaster A1 Stripped Upper Receiver in good working order. However, the color inconsistency continued to bother me, diminishing my overall satisfaction. The Bushmaster A1 Stripped Upper Receiver is functional, but its primary objective of achieving a visually accurate retro build falls flat due to the color issue.

Its reliability, as demonstrated during my range testing, is commendable. However, the color inconsistency undermines the upper’s overall appeal, especially for those seeking a visually accurate retro build.

The Bushmaster A1 Stripped Upper Receiver does not exceed expectations, particularly in terms of finish. Its functionality is solid, but the aesthetic flaw is a significant drawback. Therefore, be aware of the color issues before purchasing.

The anodized finish provides a reasonable level of corrosion resistance. Simple cleaning and lubrication are all that’s needed to keep the upper receiver in good working order.

The anodized finish should last quite a while. With proper care, this upper should last for many years.

Accessories and Customization Options
