First Impressions of Moriarti AR-15 5.56/.223 Steel Crush Washer
The Moriarti AR-15 5.56/.223 Steel Crush Washer might seem like a small, insignificant part, but it plays a crucial role in accurately and securely mounting muzzle devices on an AR-15. This seemingly simple component ensures proper timing and prevents damage to both the barrel and the attached accessory. The Moriarti name, while not as widely known as some of the bigger players, often represents a good balance of affordability and functionality in the AR parts market, so I was keen to see how this crush washer held up.
I’ve been building and modifying AR-15s for over a decade, and the bane of my existence is a muzzle device that isn’t perfectly aligned. Whether it’s a compensator, flash hider, or suppressor mount, a properly installed muzzle device is critical for accuracy, recoil management, and overall performance. Many times, I’ve struggled with shims or even tried “free-spinning” the device, only to end up with something that’s either too loose or torqued incorrectly.
My first hands-on experience was pretty straightforward. The Moriarti AR-15 5.56/.223 Steel Crush Washer arrived in a simple, no-frills package. It felt solid in my hand, with a decent weight suggesting good quality steel.
I’ve used crush washers from Bravo Company Manufacturing (BCM) and Daniel Defense in the past. While those are undoubtedly excellent, they also come with a premium price tag. I chose the Moriarti offering to see if I could achieve similar results without breaking the bank. My initial impression was that the Moriarti crush washer appeared comparable in terms of finish and overall construction.
I was cautiously optimistic. Crush washers are simple components, but a poorly made one can cause significant headaches. I was eager to see how it performed during installation and, more importantly, under live fire.
Real-World Testing: Putting Moriarti AR-15 5.56/.223 Steel Crush Washer to the Test
First Use Experience
I tested the Moriarti AR-15 5.56/.223 Steel Crush Washer during the installation of a new flash hider on my primary AR-15 build at my home workshop. This rifle is chambered in 5.56/.223 and sees regular use at the shooting range and during local 3-gun competitions. The process was straightforward: I removed the old A2 flash hider, cleaned the threads, and then prepared to install the new one with the Moriarti crush washer.
The crush washer deformed smoothly as I tightened the flash hider to the recommended torque specification, which in my case was between 20-30 ft-lbs. Proper deformation is crucial for achieving the correct timing and ensuring a secure fit. Everything felt solid, and the flash hider aligned perfectly.
No issues arose during the initial installation, which gave me confidence in its immediate usability. The experience highlighted the product’s straightforward application.
Extended Use & Reliability
After several range trips and approximately 500 rounds fired, the Moriarti AR-15 5.56/.223 Steel Crush Washer has held up admirably. There have been no signs of loosening or any change in the alignment of the flash hider. This is a critical observation, as some cheaper crush washers can lose their tension over time, leading to muzzle device wobble or even complete detachment.
The Moriarti crush washer has proven to be quite durable; there are no signs of excessive wear or deformation beyond the initial crush. This indicates that the steel is of decent quality and able to withstand the stresses of repeated firing. Maintenance for a crush washer is essentially nonexistent; once it’s installed, it’s a “set it and forget it” component.
Compared to some of the cheaper, no-name crush washers I’ve used in the past, the Moriarti offering definitely outperforms them in terms of reliability and long-term stability. It provides a secure and consistent mount, offering peace of mind that the muzzle device will stay put, even under heavy use.
