KNS Precision 1/2-36 to 5/8-24 Thread Adapter Review

Let’s Talk About KNS Precision 1/2-36 to 5/8-24 Thread Adapter

The KNS Precision 1/2-36 to 5/8-24 Thread Adapter is a simple yet essential piece of kit for any AR-15 owner looking to expand their muzzle device options. Manufactured by KNS Precision, this adapter allows you to convert a 1/2-36 RH threaded barrel, commonly found on 9mm AR platforms, to the more prevalent 5/8-24 thread pitch used for .30 caliber accessories. I was immediately drawn to its potential for versatility and the promise of simplifying my collection of muzzle devices.

I was having a real problem. I had a 9mm AR pistol with a 1/2-36 thread, and I wanted to use my .30 caliber suppressor on it. Most of my muzzle devices and suppressors are in 5/8-24, so I needed an adapter to bridge the gap.

Out of the box, the KNS Precision 1/2-36 to 5/8-24 Thread Adapter felt solid and well-made. The black nitride finish gave it a professional look, and the threads were clean and precise. Compared to some cheaper, no-name adapters I’ve seen, the KNS Precision adapter instilled immediate confidence.

I considered a few other options, including a thread adapter from a different manufacturer and even having a gunsmith re-thread the barrel. Ultimately, I chose the KNS Precision adapter for its reputation for quality and the ease of installation. My first impression was positive; this little adapter seemed like a well-engineered solution to a common problem.

First Use Experience

I tested the KNS Precision 1/2-36 to 5/8-24 Thread Adapter at my local shooting range, primarily using my 9mm AR pistol with a .30 caliber suppressor attached.
