Bushmaster AR15 Upper Parts Kit Review

First Impressions of Bushmaster AR15 Upper Parts Kit

The Bushmaster AR15 Upper Parts Kit promises to be a simple, yet essential collection of components for any AR-15 build or repair. Bushmaster, a recognizable name in the AR-15 world, offers this kit as a budget-friendly option to complete an upper receiver assembly. But does it live up to the expectations of a seasoned AR-15 enthusiast?

I was in the middle of a budget build, aiming to create a reliable yet inexpensive AR-15 for range training. After acquiring the upper receiver, barrel, and handguard, I realized I needed the small parts to complete the assembly. Instead of sourcing each individual piece, the convenience of a kit like the Bushmaster AR15 Upper Parts Kit seemed appealing.

Upon receiving the kit, I was immediately struck by the no-frills packaging. The components were neatly organized in a small plastic bag. The finish on the parts appeared consistent with what one would expect from a Bushmaster product.

Compared to buying individual parts from various manufacturers, the Bushmaster AR15 Upper Parts Kit stood out for its simplicity and low cost. I considered a similar kit from Aero Precision, known for its higher-end components, but the price difference was significant. Ultimately, the Bushmaster kit’s affordability swayed my decision.

My initial impression was cautiously optimistic. The kit seemed adequate for my budget build, though I reserved judgment until I had a chance to install and test the parts. I was hoping for reliability and functionality, even if it meant sacrificing some premium features.

Real-World Testing: Putting Bushmaster AR15 Upper Parts Kit to the Test

First Use Experience

My initial testing ground for the Bushmaster AR15 Upper Parts Kit was a local outdoor shooting range. I wanted to assess the kit’s functionality and reliability in a controlled environment. I paired the completed upper receiver with a reliable lower receiver and began cycling through various types of ammunition.

During the first session, the parts functioned without any immediate issues. The ejection port cover snapped open and closed smoothly. The forward assist engaged the bolt carrier group effectively. The range was dry and sunny, so no adverse weather conditions impacted the performance.

The parts worked right out of the bag with no needed adjustments. Initially, I was surprised at how smoothly everything worked together with zero issues.

After several months of consistent use, the Bushmaster AR15 Upper Parts Kit has proven to be a surprisingly reliable performer. I’ve put several hundred rounds through the rifle since the initial assembly. There have been no malfunctions attributed to the parts kit.

Visually, there are minimal signs of wear and tear. The finish on the ejection port cover remains intact. The forward assist button still depresses smoothly. Routine cleaning and lubrication are all that’s needed to maintain the components.

In comparison to some higher-end AR-15 builds I’ve worked on, this budget-friendly build has exceeded expectations. The Bushmaster AR15 Upper Parts Kit has delivered solid performance and reliability without breaking the bank. This has cemented my belief in the kit as a viable budget parts option.
