The Wilson Combat Spkmb1612X28 Quell K-Mount is a 1/2x28" muzzle brake engineered for .556 NATO and .223 Remington rifles. Built for shooters who run Wilson Combat Quell suppressors, this brake serves as both a recoil management device and a quick-attach interface to your suppressor system. The nitride black finish delivers the durability you need on the range or in the field, resisting corrosion and maintaining its appearance through heavy use.
If you're already invested in the Quell suppressor ecosystem, this brake simplifies your setup. Rather than juggling different mounting solutions, the K-Mount interface lets you transition smoothly between suppressed and unsuppressed shooting while keeping your point of impact consistent. The nitride finish means less maintenance headache and more time shooting.
This is purpose-built hardware for serious .223/5.56 shooters who value precision and reliability. Whether you're working precision rifle stages, hunting, or training, having a dedicated brake that matches your suppressor's mounting system removes guesswork and keeps your rig running the way it should.
| Thread Pitch | 1/2x28" |
| Caliber | .556 NATO / .223 Remington |
| Mount Type | K-Mount (Quell Suppressors) |
| Finish | Nitride Black |
| Brand | Wilson Combat |
Yes. The K-Mount interface on this brake is specifically designed to work with the Quell suppressor line, allowing you to attach and detach your suppressor quickly and repeatably.
This brake is threaded for .556 NATO and .223 Remington rifles with 1/2x28" barrel threads.
If your AR-15 has a barrel threaded 1/2x28" and fires .556 NATO or .223 Remington, yes. Check your barrel's thread pitch before ordering.
Nitride is a hard, durable finish that resists corrosion. Standard firearm care—keeping it reasonably clean and dry—is sufficient to maintain it long-term.
