Lantac 1/2-28 Plan B Longlantac Dragon Muzzle Brake 9Mm$128.99
Availability: In Stock
The Lantac Dragon Plan B muzzle brake for .223/5.56mm rifles delivers serious recoil management in a precision-engineered package designed for shooters who demand repeatability and control. This 1/2-28 threaded brake features Lantac's proprietary Short Energy Pulse system, engineered to collapse recoil duration so that shot-to-shot impulses don't stack and throw you off target. Whether you're running fast repeating fire at the range or hunting, the Dragon Plan B works to keep muzzle rise minimal and shot grouping tight.
Built from AISI 4140 steel hardened to 48-52 Rockwell C and finished with QPQ nitriding per AMS2753D standards, this brake is constructed to handle serious use and harsh conditions. Lantac machines each unit on Swiss lathes and serial numbers them for quality control. The mounting system integrates with the Plan-B hub standard, giving you the flexibility to swap suppressors or configure your setup without committing to a single platform. At 2.575 inches long with a 0.900-inch mount diameter, it strikes a balance between effectiveness and practicality on most modern .223 builds.
The brake ships with a timing shim set, so you can dial in zero-timing right out of the box. Lantac recommends using Rocksett (sold separately) for assembly. This is a quality American-made part backed by real engineering—no licensing shortcuts, just straightforward recoil reduction for shooters who value precision.

The Lantac Dragon Plan B uses a 1/2-28 thread pitch, the standard for .223/5.56mm rifles. Make sure your barrel is threaded to this specification before ordering.
The Dragon Plan B features a Plan-B hub mount design, which is compatible with suppressor systems that accept the Plan-B standard. However, this mount design is not licensed from Q, so suppressor warranty may be affected depending on the suppressor manufacturer. Check with your suppressor maker before pairing them.
Each brake ships with a timing shim set to help you achieve proper timing during installation. Lantac recommends using Rocksett thread locker (sold separately) for assembly.
The brake is machined from AISI 4140 steel hardened to 48–52 Rockwell C and then QPQ nitrided to AMS2753D standards. This finish provides extreme corrosion resistance and extended service life under heavy use.
