Bushmaster .308 Winchester Crush Washer Review

First Impressions of Bushmaster .308 Winchester Crush Washer

The Bushmaster .308 Winchester Crush Washer, a seemingly insignificant piece of metal, is a vital component for any AR-10 platform rifle chambered in .308 Winchester. This little washer plays a crucial role in properly timing muzzle devices, ensuring optimal performance and safety. I picked up a few of these recently, not out of excitement, but out of necessity: a crucial step in upgrading my .308 AR-10 with a new muzzle brake.

When I first received the Bushmaster .308 Winchester Crush Washer, I wasn’t exactly blown away by its appearance. It’s a small, black washer, seemingly unremarkable. However, picking it up, I noted its solid feel and the precise machining evident in its construction, hinting at a quality component despite its simplicity.

Compared to generic crush washers I’ve used in the past, the Bushmaster offering appears to be made of a slightly harder, more durable material. Many cheaper alternatives often feel soft and easily deform, potentially leading to inconsistent muzzle device timing. While a seemingly small difference, I hoped this would translate to more consistent performance during installation. I also considered a shim kit, but for this particular muzzle device, a crush washer seemed sufficient for proper alignment. My initial thought was cautiously optimistic – hoping this little piece of steel would live up to its crucial role.

Real-World Testing: Putting Bushmaster .308 Winchester Crush Washer to the Test

First Use Experience

My first use of the Bushmaster .308 Winchester Crush Washer was during the installation of a new muzzle brake on my AR-10. The installation took place in my workshop, a relatively controlled environment. I carefully followed the manufacturer’s instructions, paying close attention to the torque specifications.

The Bushmaster crush washer deformed smoothly as I tightened the muzzle brake, allowing for precise timing. Unlike some cheaper washers I’ve used, it didn’t bind or require excessive force to crush. The initial results seemed promising – the muzzle brake was timed correctly, and there were no signs of gas leakage.

Extended Use & Reliability

After several range trips and approximately 300 rounds fired with the new muzzle brake and Bushmaster .308 Winchester Crush Washer installed, I’m happy to report it’s held up perfectly. There’s been no shift in the muzzle device timing and no indication of any gas leakage around the threads. The installation remains solid.

I’ve inspected the washer after each range session, and there are no signs of excessive wear or deformation beyond the initial crushing. The black finish is still intact. Cleaning is as simple as wiping down the muzzle device and surrounding area, requiring no special care for the crush washer itself. It definitely outperformed some cheaper, generic crush washers I’ve used, which tended to loosen or crumble after repeated use.

Breaking Down the Features of Bushmaster .308 Winchester Crush Washer

Specifications

• The Bushmaster .308 Winchester Crush Washer is specifically designed for .308 Winchester AR-10 platform rifles. This ensures a proper fit and seal for muzzle devices designed for this caliber.
• It features a black finish, likely a phosphate coating, offering corrosion resistance. This is a crucial factor, as the muzzle of a rifle is exposed to harsh environments and corrosive gases.
• The washer is made from a durable steel alloy, designed to deform under pressure while maintaining structural integrity. This ensures a secure seal and prevents the muzzle device from loosening during firing.
• The dimensions are precise, conforming to industry standards for .308 muzzle devices. This ensures compatibility with a wide range of brakes, compensators, and flash hiders.

Performance & Functionality

The Bushmaster .308 Winchester Crush Washer performs its primary function of sealing and timing muzzle devices admirably. It creates a tight gas seal, preventing propellant gases from escaping around the threads, which can degrade performance and damage the threads themselves. The crush design allows for precise alignment of the muzzle device.

Its strength lies in its consistent and reliable performance; its weakness, if any, is its single-use nature. Once crushed, it should be replaced for optimal performance with a new muzzle device installation. It definitely meets my expectations for a part that ensures the safe and optimal operation of a firearm.

Design & Ergonomics

The design of the Bushmaster .308 Winchester Crush Washer is simple and functional. It is a flat, circular washer with a specific thickness designed to crush under a predetermined torque. The black finish aids in corrosion resistance and blends in aesthetically with most muzzle devices.

There is no real “ergonomics” to speak of, as it’s an internal component. However, its ease of installation and the precise timing it allows make it a user-friendly component, even for novice gunsmiths.

Durability & Maintenance

The Bushmaster .308 Winchester Crush Washer is a durable component designed for single use. While it may appear reusable, it’s crucial to replace it after each muzzle device installation to ensure optimal performance. Maintenance is virtually non-existent.

The part itself requires no specific cleaning or care beyond a visual inspection for damage before installation. Provided it’s properly installed and torqued, it should last the lifespan of a single muzzle device installation.

Accessories and Customization Options

The Bushmaster .308 Winchester Crush Washer is primarily a functional component and doesn’t lend itself to customization in the traditional sense. It doesn’t come with accessories, being a standalone part.

Its compatibility with a wide range of .308 muzzle devices is its key strength in terms of customization. It seamlessly integrates with various brakes, compensators, and flash hiders from different brands, allowing users to fine-tune their rifle’s performance.

Who Should Buy Bushmaster .308 Winchester Crush Washer?

The Bushmaster .308 Winchester Crush Washer is perfect for anyone who owns an AR-10 chambered in .308 Winchester and plans to install or change their muzzle device. This includes competitive shooters looking to fine-tune recoil management, hunters seeking to reduce muzzle flash, and casual shooters wanting to improve their rifle’s performance.

Those who should skip this product are individuals who are unwilling to replace the crush washer after each use, as reusing a crush washer can lead to improper timing and potentially dangerous situations. Additionally, if your muzzle device requires a specific shim kit for timing, this product won’t be suitable. A torque wrench is a must-have accessory for proper installation.
