ARMASPEC ARM2961-BLK CATACOMB MICRO BRK 223 1/2X28

The Armaspec Catacomb Micro muzzle brake is a compact brake designed for AR-15s and other rifles chambered in .223/5.56 NATO with 1/2"x28 threaded muzzles. Built for shooters who want recoil management without the bulk, this micro brake delivers the core functionality of a full-size brake in a streamlined package—ideal if you're running a shorter barrel, keeping your overall rig tight, or just prefer a cleaner profile on your rifle. The QPQ nitride finish resists corrosion and wear, holding up under regular use at the range or in the field.

Armaspec engineered the Catacomb with a ported design that works to redirect muzzle gases and reduce felt recoil and muzzle rise. On a .223 platform, that means faster target reacquisition and less fatigue during extended shooting sessions, whether you're working through a precision rifle course, hunting, or putting rounds downrange for fun. The compact footprint keeps your rifle balanced and manageable, and the black finish integrates cleanly with most builds.

Installation is straightforward for anyone comfortable working on their rifle: simply thread it onto a 1/2"x28 muzzle and time it as needed. The QPQ nitride coating is durable and corrosion-resistant, so it'll weather regular cleaning and outdoor use without degrading. This is a no-nonsense brake that does its job without excessive weight or size.

Specifications

Frequently Asked Questions

Will this brake fit my AR-15?

Yes, if your AR-15 is chambered in .223 or 5.56 NATO and has a 1/2"x28 threaded muzzle. If you're unsure whether your barrel has that thread pattern, measure the threads or check your barrel manufacturer's specs before ordering.

What's the advantage of a micro brake over a full-size brake?

Micro brakes like the Catacomb deliver meaningful recoil reduction and improved sight picture in a smaller, lighter package. They're particularly useful on short-barrel rifles, SBRs, or builds where you want to keep the overall profile compact and manageable without sacrificing performance.

How do I install this muzzle brake?

Thread it onto your 1/2"x28 muzzle, then time (rotate) it to your preferred position using a reaction rod or armorer's wrench. If you're unfamiliar with the process, have a qualified gunsmith handle it.

Is the QPQ nitride finish durable?

Yes. QPQ nitride is a proven finishing process that provides corrosion resistance and hardness. It holds up well to cleaning solvents, outdoor exposure, and regular shooting use.
