First Impressions of Brenton USA Tracker 22in .450 Bushmaster Upper Receiver
The Brenton USA Tracker 22in .450 Bushmaster Upper Receiver promises unwavering performance for the dedicated hunter, and that’s a promise that immediately piqued my interest. As a seasoned outdoorsman and tactical gear specialist, I’m always on the lookout for equipment that can withstand the rigors of demanding hunts and challenging environments. The Brenton USA name carries a reputation for quality, and the .450 Bushmaster caliber is a powerhouse for big game.
I needed a reliable and accurate upper receiver for my AR-15 platform, specifically chambered in .450 Bushmaster, for hunting whitetail deer in thick brush. The ability to quickly and ethically harvest game in close quarters is paramount, and the .450 Bushmaster is known for its stopping power. After years of using various AR setups, I wanted something specifically tailored for hunting, with guaranteed sub-MOA accuracy.
Unboxing the Brenton USA Tracker 22in .450 Bushmaster Upper Receiver, I was immediately impressed by the fit and finish. The receiver felt solid and well-constructed, and the Brenton RealFeel PolyCore handguard provided a comfortable and secure grip. The weight, at 5.18 lbs, felt balanced and manageable, suggesting a well-engineered system.
I considered other .450 Bushmaster uppers from companies like Bushmaster and Bear Creek Arsenal. However, the Brenton USA upper stood out because of its lifetime warranty and sub-MOA guarantee. The included features, like the Brenton Patent Pending RecevierLock and the Gas diverting Charge Handle, also swayed my decision.
My first impression was one of excitement and cautious optimism. The Brenton USA Tracker 22in .450 Bushmaster Upper Receiver appeared to be a high-quality, purpose-built hunting tool. It held the promise of exceptional performance and reliability, but only real-world testing would reveal its true potential.
Real-World Testing: Putting Brenton USA Tracker 22in .450 Bushmaster Upper Receiver to the Test
First Use Experience
I first tested the Brenton USA Tracker 22in .450 Bushmaster Upper Receiver at my local shooting range, zeroing it in preparation for deer season. I paired it with a trusted lower receiver and mounted a high-quality 3-9×40 scope. The weather was mild, with a slight breeze, providing ideal shooting conditions.
The upper performed flawlessly right out of the box. The mid-length gas system ensured smooth cycling, and the recoil, while significant, was manageable. I was able to achieve sub-MOA accuracy with Hornady Custom 250gr FTX ammunition, validating Brenton’s sub-MOA guarantee.
After the initial range session, I noticed no immediate issues. The upper was easy to install and functioned without any hiccups. The Gas diverting Charge Handle proved effective in minimizing gas blowback to the face.
Extended Use & Reliability
After several weeks of use, including multiple range trips and a week-long deer hunting expedition, the Brenton USA Tracker 22in .450 Bushmaster Upper Receiver continued to impress. The finish remained pristine, showing no signs of wear or corrosion. The handguard stayed secure, even after being subjected to rough handling in the field.
Cleaning the upper was straightforward. The 416R Stainless Steel barrel cleaned up easily, and the NiB protective coating on the bolt carrier group (BCG) made it resistant to carbon buildup. The upper proved to be incredibly reliable, with no malfunctions or failures to feed.
Compared to my previous .450 Bushmaster upper from a different manufacturer, the Brenton USA model offered a significant improvement in accuracy and overall build quality. The Brenton USA Tracker 22in .450 Bushmaster Upper Receiver consistently delivered sub-MOA performance, while my previous upper struggled to maintain 2 MOA. This upper has far exceeded my expectations.
