Wilson Combat Spkmb1612X28 Quell K-Mount 1/2X28" Nitride Black

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.
