UPPER GROUP BANSHEE 5.7X28MM 5in Armor Black Review

First Thoughts on the UPPER GROUP BANSHEE 5.7X28MM 5in Armor Black

The UPPER GROUP BANSHEE 5.7X28MM 5in Armor Black is a unique offering in the AR pistol market, chambered in the high-velocity 5.7x28mm round. This particular model, with its 5-inch barrel and sleek Armor Black Cerakote finish, immediately caught my eye as something different from the standard 9mm or .223/5.56 AR pistols. The 5.7x28mm cartridge has always intrigued me, promising flat trajectories and impressive terminal ballistics in a compact package.

I was searching for a compact, high-velocity platform suitable for varmint control and potentially personal defense, where over-penetration was a significant concern. I wanted something maneuverable and easy to deploy from a vehicle or tight space. The UPPER GROUP BANSHEE seemed to fit the bill, offering a blend of AR ergonomics and the 5.7x28mm’s inherent advantages.

Unboxing the UPPER GROUP BANSHEE, my first impression was positive. The Armor Black Cerakote finish looked even better in person, offering a smooth, consistent coating that should provide excellent corrosion resistance. The upper felt solid and well-built, with no noticeable play or looseness. Compared to some of the budget AR pistols I’ve handled, the BANSHEE exudes a sense of quality.

I considered other options like the Ruger-57 pistol and the FN Five-seveN, but those are handguns, not pistol caliber carbines. I also looked at other 5.7x28mm AR uppers, but the BANSHEE’s overall aesthetic and reputation for reliability swayed my decision. I wasn’t disappointed.

My initial excitement was definitely justified. The UPPER GROUP BANSHEE 5.7X28MM 5in Armor Black presented itself as a well-designed and well-executed platform that deserves serious consideration for anyone interested in the 5.7x28mm cartridge.

Real-World Testing: Putting UPPER GROUP BANSHEE 5.7X28MM 5in Armor Black to the Test

First Use Experience

I tested the UPPER GROUP BANSHEE at my local outdoor shooting range, under relatively dry conditions. The temperature was around 70 degrees Fahrenheit, with a slight breeze. I paired the upper with a mil-spec AR-15 lower receiver I had on hand, and used both FN and Federal American Eagle 5.7x28mm ammunition.

The first few magazines were a blast (pun intended!). The recoil was minimal, as expected from the 5.7x28mm round in an AR platform. I was able to quickly acquire targets and maintain accuracy even during rapid fire. The included flash hider did a decent job of mitigating muzzle flash, which is particularly noticeable with this cartridge. After the first 100 rounds, no issues or failures were noted.

Extended Use & Reliability

After several months of regular use, the UPPER GROUP BANSHEE has proven to be remarkably reliable. I’ve put approximately 500 rounds through it, with only one malfunction – a failure to extract, which I attribute to a slightly dirty chamber after prolonged use.

The Armor Black Cerakote finish has held up exceptionally well, showing no signs of wear or scratches, even after being bumped around in my range bag. Cleaning and maintenance are straightforward. Standard AR-15 cleaning procedures apply, and the 5.7x28mm round leaves relatively little residue compared to other pistol cartridges.

Compared to my previous experiences with other AR pistols, the BANSHEE stands out in terms of reliability and accuracy. While some AR pistols can be finicky with different types of ammunition, the UPPER GROUP BANSHEE has cycled everything I’ve fed it with minimal issues. The minimal recoil of this system is also a big plus for extended shooting sessions.

Breaking Down the Features of UPPER GROUP BANSHEE 5.7X28MM 5in Armor Black

Specifications

The UPPER GROUP BANSHEE 5.7X28MM 5in Armor Black boasts some impressive specifications. It is chambered in 5.7x28mm, a high-velocity, low-recoil cartridge known for its flat trajectory. The barrel length is 5 inches, making it exceptionally compact and maneuverable.

• Caliber: 5.7x28mm
• Barrel Length: 5″
• Twist Rate: 1:9″
• Receiver Finish: Black Armor Cerakote

The 1:9″ twist rate is optimized for stabilizing the standard 40-grain 5.7x28mm projectiles. The Armor Black Cerakote finish provides excellent corrosion resistance and a sleek, professional look. These specifications translate to a highly effective and durable firearm.

Performance & Functionality

The UPPER GROUP BANSHEE excels in both performance and functionality. Accuracy is excellent, particularly at shorter ranges (out to 50 yards). The minimal recoil allows for fast follow-up shots and precise targeting. The short barrel does result in some velocity loss compared to longer 5.7x28mm platforms, but this is a trade-off for its compact size.

The main strength is its reliability. The direct impingement gas system, combined with the high-quality components, ensures consistent cycling and minimal malfunctions. A potential weakness could be the shorter dwell time due to the 5″ barrel, which could potentially lead to increased wear on internal components over the long term with high round counts, though I have not experienced this. So far, the UPPER GROUP BANSHEE meets and slightly exceeds my expectations.

Design & Ergonomics

The UPPER GROUP BANSHEE features a well-thought-out design. The Armor Black Cerakote finish not only looks good but also provides a smooth, comfortable grip. The overall weight is relatively light, making it easy to handle and maneuver.

There’s no real learning curve. If you’re familiar with the AR-15 platform, you’ll feel right at home. The controls are intuitive, and the ergonomics are generally excellent.

Durability & Maintenance

The UPPER GROUP BANSHEE is built to last. The high-quality materials and robust construction ensure that it can withstand heavy use. As mentioned earlier, the Cerakote finish provides excellent protection against corrosion and wear.

Maintenance is simple. Standard AR-15 cleaning procedures are sufficient to keep it running smoothly. The 5.7x28mm round is relatively clean-burning, which helps to minimize fouling.

Accessories and Customization Options

The UPPER GROUP BANSHEE offers ample customization options. It is compatible with any standard AR-15 lower receiver, allowing you to choose your preferred stock, grip, and trigger.

The flattop receiver provides a generous amount of rail space for mounting optics, such as red dot sights or holographic sights. Many aftermarket accessories are available for the 5.7x28mm AR platform, including different muzzle devices, charging handles, and bolt carrier groups. The compatibility with standard AR-15 lowers is a significant advantage.
