Bushmaster Bravo Zulu Upper Assembly Review

First Impressions of Bushmaster Bravo Zulu Upper Assembly

The Bushmaster Bravo Zulu Upper Assembly promises a blend of quality and affordability, making it an intriguing option for AR-15 enthusiasts. As someone with over a decade of experience in the tactical gear world, I’m always on the lookout for products that deliver performance without breaking the bank. This upper assembly, featuring a Bushmaster barrel with a Salt Bath Nitride finish and a 10″ M-LOK handguard, certainly piqued my interest. I was hoping this would be a great “drop-in” upper to breathe new life into an older build.

I was drawn to the Bravo Zulu Upper Assembly because I was looking for a reliable and accurate upper to pair with a lower receiver I had sitting unused. My main requirements were a mid-length gas system for smoother recoil and an M-LOK handguard for accessory mounting flexibility. Other options felt like overkill for my intended purpose of recreational target shooting and potential home defense.

Upon unboxing, the Bravo Zulu Upper Assembly presents itself well. The finish is clean, and the components appear to be of decent quality. The weight feels balanced. The M-LOK handguard feels solid and provides ample space for attachments. Compared to some other budget-friendly uppers I’ve handled, the Bushmaster offering seemed to have a more refined fit and finish. My initial impression was cautiously optimistic; it seemed like a solid foundation, even if the fit was a “little loose.”

I did consider a complete upper from Palmetto State Armory and Aero Precision before settling on the Bushmaster Bravo Zulu Upper Assembly. PSA is known for its affordability, but I wanted something a little more refined. Aero Precision is generally excellent, but more expensive. The Bushmaster seemed to offer a sweet spot between price and features.

Initially, I was excited about the prospect of a high-quality, American-made upper at this price point. The “little loose fitting” comment from another user gave me a bit of pause, but I decided to proceed, hoping that it wouldn’t impact performance too severely.

Real-World Testing: Putting Bushmaster Bravo Zulu Upper Assembly to the Test

First Use Experience

I first tested the Bravo Zulu Upper Assembly at my local shooting range. The weather was clear and sunny, around 70 degrees Fahrenheit, perfect conditions for zeroing a new optic. I mounted a red dot sight and used a variety of .223 and 5.56 ammunition to see how the upper performed with different loads.

The first few magazines went smoothly. The mid-length gas system did indeed provide a noticeable reduction in felt recoil compared to a carbine-length system, making for a more comfortable shooting experience. I also appreciated the included Snake Charmer Muzzle Brake. It further mitigated muzzle rise. The upper functioned reliably with both brass and steel-cased ammunition.

However, after about 100 rounds, I did experience a few failures to extract. This was a bit concerning. I attributed it to either the upper still being “new” or the cheaper steel-cased ammo. I added some lubrication and continued.

Extended Use & Reliability

After several weeks of use, and several hundred more rounds, the Bravo Zulu Upper Assembly has proven to be reasonably reliable. The failures to extract issue lessened considerably after the initial break-in period. I now primarily use brass-cased ammunition. This appears to have solved the problem entirely.

There are no significant signs of wear and tear after several range sessions. The Salt Bath Nitride finish on the barrel seems to be holding up well. I’ve cleaned the upper after each use, which is a straightforward process. The bolt carrier group disassembles easily.

Compared to a previous, budget-friendly upper I owned, the Bravo Zulu Upper Assembly is definitely a step up in terms of overall quality and shooting comfort. However, it doesn’t quite reach the level of performance I’ve experienced with higher-end uppers from companies like Daniel Defense or Bravo Company Manufacturing. It meets expectations for its price point.
