First Impressions of Kexuan .450 Bushmaster Crush Washer Set, 10 Piece
As someone deeply entrenched in the world of firearms, particularly the AR platform, I’ve learned that the smallest components can make the biggest difference in performance and reliability. When I first saw the Kexuan .450 Bushmaster Crush Washer Set, 10 Piece, I was intrigued by its promise of providing a cost-effective solution for ensuring proper muzzle device installation on my .450 Bushmaster AR builds. Are these crush washers truly up to the task of indexing muzzle devices safely and securely?
My primary motivation for acquiring this set stemmed from the need to consistently and correctly install muzzle brakes on my .450 Bushmaster AR-15. This caliber, known for its substantial recoil, demands precision in muzzle device mounting to maximize recoil reduction and maintain accuracy. Improper indexing can lead to decreased effectiveness or even damage to the firearm.
Upon receiving the package, I was immediately impressed by the organized presentation of the washers. The weight felt appropriate for the intended use, and the material appeared to be of decent quality. Compared to some generic crush washers I’ve encountered, these seemed more precisely manufactured.
I’ve used similar crush washers from brands like Yankee Hill Machine and Smith Enterprise in the past. However, those options are significantly more expensive. The Kexuan .450 Bushmaster Crush Washer Set, 10 Piece was chosen for its appealing price point and the potential for bulk use in multiple builds.
My initial feeling was cautiously optimistic. While I was eager to put them to the test, I also held a degree of skepticism, hoping they would live up to their promise without compromising safety or performance.
Real-World Testing: Putting Kexuan .450 Bushmaster Crush Washer Set, 10 Piece to the Test
First Use Experience
The initial testing ground for the Kexuan .450 Bushmaster Crush Washer Set, 10 Piece was my local shooting range, specifically the AR rifle section. I utilized these crush washers during the installation of a new muzzle brake on my primary .450 Bushmaster AR-15. The weather was mild and dry, providing optimal conditions for observing performance without environmental interference.
The crush washers proved to be reasonably easy to use, requiring only standard tools and techniques for muzzle device installation. I didn’t need any special tools or tricks to get them properly installed. However, I did notice they required a bit more torque to crush than higher-end washers.
Initially, I was pleased with the perceived alignment and secure fit of the muzzle brake. However, after about 20 rounds, I noticed the brake had slightly rotated from its intended position. This raised some concerns about the long-term reliability of the crush washers.
Extended Use & Reliability
After several weeks and approximately 200 rounds fired, the Kexuan .450 Bushmaster Crush Washer Set, 10 Piece has exhibited mixed performance. While the initial set-up seemed promising, the consistency of the crush washers over time has been questionable. One crush washer remained securely in place, while another exhibited further rotation after about 100 rounds.
There are no visible signs of significant wear and tear on the washers themselves; however, the inconsistency in their performance raises concerns about their durability under the intense pressures of the .450 Bushmaster cartridge. The cleaning and maintenance are straightforward, as the crush washers are disposable and do not require specific care. Compared to my experiences with premium crush washers, the Kexuan .450 Bushmaster Crush Washer Set, 10 Piece falls slightly short in terms of consistent, long-term reliability.
Breaking Down the Features of Kexuan .450 Bushmaster Crush Washer Set, 10 Piece
Specifications
The Kexuan .450 Bushmaster Crush Washer Set, 10 Piece is specifically designed for use with .450 Bushmaster AR-15 rifles. These washers are intended to ensure proper indexing of muzzle devices, such as muzzle brakes and flash hiders. The set includes ten individual crush washers, providing multiple uses for different builds or replacements.
The washers are manufactured from a steel alloy, which offers sufficient strength to withstand the pressures of crushing during installation. The precise dimensions of the crush washers ensure compatibility with standard .450 Bushmaster barrel threads, allowing for a secure fit. The crush washers are a critical component, as they allow the user to correctly time/align muzzle devices.
Performance & Functionality
The primary function of the Kexuan .450 Bushmaster Crush Washer Set, 10 Piece is to allow for the proper timing and secure attachment of muzzle devices on .450 Bushmaster rifles. When properly installed, the crush washer creates a tight seal between the barrel and the muzzle device, preventing loosening due to recoil. While they generally perform this task adequately, the inconsistencies I experienced raised concerns.
The strengths of this product lie in its affordability and the convenience of having multiple washers in a single set. However, the primary weakness is the inconsistency in the crushing and long-term security provided. While they meet basic expectations, they fall short of providing the rock-solid confidence that premium crush washers offer.
Design & Ergonomics
The design of the Kexuan .450 Bushmaster Crush Washer Set, 10 Piece is straightforward and functional. The crush washers are simple rings of metal designed to deform under pressure. The build quality appears adequate for the intended purpose, though there is a noticeable difference in the finishing compared to higher-end options.
The Kexuan .450 Bushmaster Crush Washer Set, 10 Piece is very user-friendly and presents no real learning curve. Anyone familiar with AR-15 builds should be able to use them with ease.
Durability & Maintenance
The durability of the Kexuan .450 Bushmaster Crush Washer Set, 10 Piece is somewhat questionable based on my experiences. While the material seems robust enough, the inconsistency in performance suggests they may not hold up as well over extended periods of heavy use. These are not intended for reuse.
Maintenance is not a concern, as the crush washers are intended to be disposable after each installation. No special cleaning or care is required.
Accessories and Customization Options
The Kexuan .450 Bushmaster Crush Washer Set, 10 Piece does not come with any additional accessories. It is a standalone product intended to be used with existing muzzle devices. These crush washers are compatible with any standard .450 Bushmaster muzzle device.

Conclusion on Kexuan .450 Bushmaster Crush Washer Set, 10 Piece
The Kexuan .450 Bushmaster Crush Washer Set, 10 Piece presents a mixed bag. While it offers an attractive price point and the convenience of a ten-piece set, the inconsistencies in performance and long-term reliability raise some concerns.

Would I personally recommend it? For budget builds and casual shooting, yes, with the caveat that you should check the muzzle device frequently for any signs of loosening. However, for serious applications where performance and reliability are paramount, I would advise investing in higher-quality crush washers. If you are on a budget and need crush washers, give these a try, but be sure to check the alignment often.
