The KNS Precision thread adapter converts 1/2x28 barrels to accept 5/8x24 muzzle devices—a practical solution for shooters who want to run standard .30-caliber suppressors, brakes, or flash hiders on .223/5.56 rifles with smaller bore threads. If you've invested in 5/8x24 cans or brakes but your AR or other platform wears a 1/2x28 barrel, this adapter bridges that gap without a trip to the gunsmith. It's straightforward, reliable, and lets you consolidate your muzzle device collection across multiple builds.
KNS Precision engineered this adapter with simplicity in mind: you get a solid threaded interface with a 5/8x24 outside diameter (female threads for your muzzle device) and a 1/2x28 bore that screws directly onto your barrel. Installation is a basic wrench job—a 5/8-inch wrench is all you need to snug it down. No special tools, no complicated procedures. The result is a rock-solid connection that lets your existing suppressors and brakes work on barrels they weren't originally designed for.
This adapter is particularly handy if you're running a precision .223 build or modernizing an older platform. Rather than replacing a barrel or leaving quality muzzle devices in your parts bin, you get a second life out of hardware you already own. It's the kind of understated, practical part that makes the difference between a rifle that works exactly how you want and one that doesn't quite fit your setup.

| Tool Required | 5/8-inch wrench |
Yes. The adapter accepts 1/2x28 barrels (the standard thread pitch on most .223 and 5.56 rifles) and outputs 5/8x24, which is the common thread pattern for .30-caliber suppressors and brakes.
Any suppressor, brake, flash hider, or other muzzle device with 5/8x24 female threads will fit. This includes the vast majority of .30-caliber-rated units on the market.
No. A 5/8-inch wrench is the only tool needed. Simply screw it onto your 1/2x28 barrel and tighten it down. No special equipment or labor required.
The adapter itself is a thread converter and works with any barrel that has 1/2x28 threads. Compatibility depends on the barrel, not the caliber—check your barrel's thread specification before purchasing.
