Lantac Dragon Muzzle Brake 223/5.56 1/2-28

The Lantac Dragon muzzle brake for .223/5.56 AR-15s is a precision-engineered device designed to cut recoil and muzzle rise so you stay on target—especially valuable if you're running rapid fire or want flatter shot groups at distance. Built from AISI 4140 steel hardened to 48–52 Rockwell C and finished with QPQ nitriding to AMS2753D standards, this is a brake made to handle serious use without rusting out. It's manufactured in the USA on Swiss lathes, which shows in the tight tolerances and clean machining.

The Dragon uses what Lantac calls a Short Energy Pulse system to manage the timing of recoil events, so the rearward forces don't stack up and pile-drive you off your sight picture. That translates to better control in semi-auto strings and noticeably less vertical climb in rapid or full-auto fire. The brake ships with a timing shim set to dial in concentricity with your barrel, and it threads on with a 1/2-28 pattern—standard for most modern .223 uppers.

One detail worth knowing: this is a Plan-B Hub Mount design that is not licensed from Q LLC. If suppressor compatibility matters to your setup, check Q's guidance on third-party brakes before buying. We recommend using Rocksett (sold separately) for semi-permanent installation. The brake comes serial-numbered for quality control and will serve well on hunting ARs, competition rifles, and range guns where you need reliable recoil management and durability.

Frequently Asked Questions

Will this brake work with my .223 or 5.56 AR-15?

Yes. The Lantac Dragon is chambered for .223 / 5.56mm and uses a 1/2-28 thread pattern, which is the standard on most modern .223 and 5.56 uppers.

Is this brake suppressor-compatible?

The Dragon uses a Plan-B Hub Mount design that is not licensed from Q LLC. If you're planning to run a suppressor, check Q's documentation and compatibility guidance for third-party brakes before purchasing.

What comes in the box?

The brake ships with a timing shim set to help align it concentrically with your barrel. We recommend using Rocksett (sold separately) for semi-permanent installation.

How much recoil reduction does this provide?

The Short Energy Pulse system is engineered to reduce recoil stacking and muzzle rise, particularly noticeable in rapid or full-auto fire. For exact performance data, contact Lantac directly or check independent reviews.
