Frequently Asked Questions
Will the LANTAC Dragon fit my AR-15 barrel?
The LANTAC Dragon DGN556B is threaded at 1/2x28, which is the industry-standard thread pitch for AR-15, M16, and M4 barrels chambered in 5.56 NATO or .223 Remington. As long as your barrel has a 1/2x28 threaded muzzle — which is standard on the vast majority of factory AR-15 barrels — the Dragon will install directly using the included crush washer. Always verify your barrel's thread pitch before purchase if you're unsure.
How does the Short Energy Pulse system actually reduce recoil?
LANTAC's Short Energy Pulse (SEP) technology works by rapidly venting propellant gases through the Dragon's precisely angled ports, which counteracts rearward recoil force and suppresses muzzle rise simultaneously. Crucially, the system is designed to shorten the duration of the recoil impulse so that the energy from one shot fully dissipates before the next round fires — preventing recoil "stacking" that can push a shooter off their point of aim during rapid or full-auto fire. The result is faster, more accurate follow-up shots.
Is the LANTAC Dragon compatible with a suppressor?
The LANTAC Dragon DGN556B is a standalone muzzle brake and is not designed as a suppressor mount or quick-detach adapter. If you plan to run a suppressor on your AR-15, you would need a suppressor-compatible mount or a direct-thread suppressor that matches the 1/2x28 thread. For suppressor-ready builds, LANTAC also offers the DRAGON-QD variant designed to work with compatible quick-detach suppressor systems.
