The LANTAC Dragon Plan B Short is a two-in-one deal: a serious recoil-taming muzzle brake up front and a Plan-B HUB mounting interface for shooters who plan to run a suppressor. At just 1.75 inches long, it keeps your barrel profile trim while still delivering the aggressive braking LANTAC's Dragon line is known for. It's threaded 5/8×24 and covers a wide swath of .30-caliber and big-bore chamberings including 6.5 Creedmoor, 7.62/.308, 300 Blackout, .338 ARC, and 300 Win Mag.
The heart of this brake is LANTAC's Short Energy Pulse system. The idea is straightforward: it shortens the length of the recoil impulse so that the energy from one shot doesn't overlap and shove you off target before the next round. In plain terms, you keep your sight picture and get back on target faster. Muzzle rise gets knocked way down too, which is exactly what you want on hard-recoiling calibers where follow-up speed matters.
These aren't cast or budget parts. Each Dragon brake is precision-machined on Swiss lathes from AISI 4140 steel, then hardened to roughly 55 Rc and QPQ nitrided to AMS2753D standards. That treatment gives you serious corrosion resistance, a slick black finish, and the kind of durability that holds up to heat and heavy round counts. It ships with a timing shim set to get everything indexed correctly during install.
The short-profile hub interface lets you mount a Plan-B compatible suppressor using a taper-on-taper lockup, which gives repeatable point of impact and keeps carbon off your threads. If you're building a can-ready rifle and want a brake that pulls double duty, this is a smart pick. LANTAC recommends a semi-permanent thread locker like Rocksett for installation, and it's worth following the HUB shooting guidance from your suppressor maker before you send rounds through a mounted can.
It's a .30-caliber brake with 5/8×24 threading, so it covers a broad range of chamberings including 6.5 Creedmoor, 7.62/.308, 300 Blackout, .338 ARC, and 300 Win Mag. Make sure your barrel is threaded 5/8×24 before ordering. As with any brake sized for a range of bores, confirm your specific caliber has proper bore clearance.
Yes, that's the whole point of the Plan-B design. The short-profile hub interface accepts Plan-B compatible suppressors and adapters using a taper-on-taper lockup, which gives you repeatable point of impact and keeps carbon off the threads. Just make sure your can or adapter is confirmed Plan-B compatible before running it.
This brake ships with a timing shim set rather than a crush washer, which lets you index it precisely. LANTAC recommends using a semi-permanent thread locker like Rocksett during install, which is sold separately.
LANTAC's Short Energy Pulse system is built to shorten the recoil impulse so shot energy doesn't overlap and push you off target between rounds. Real-world users of the Dragon line consistently report a big drop in muzzle climb and noticeably softer felt recoil. The tradeoff, like any effective brake, is more side blast and noise for anyone standing nearby.
