223/5.56 1/2-28 PLAN B LONGLANTAC LAMPREY FLASH COMP

The Lantac Lamprey flash hider for 223/5.56 AR-15 platforms brings serious flash reduction to your rifle without sacrificing gun control. This 1/2-28 threaded muzzle device uses a patented design—that distinctive toothed four-tine profile—to disrupt powder gases more aggressively than conventional prongs, cutting muzzle flash intensity and duration in ways that matter when you're shooting in low light or need to preserve your night vision. It's built for shooters who demand reliability and performance in the field, whether you're running a precision rifle at the range or a duty-ready AR in tactical conditions.

What sets the Lamprey apart is the internal baffle system that works with those vertical ports to manage gas flow more efficiently than traditional brake designs. The result is noticeably reduced recoil impulse, giving you faster follow-up shots and steadier sight picture. Better still, the Lantac Lamprey is fully compatible with the Plan-B HUB system—a growing ecosystem of modular AR components that lets you swap suppressors, brakes, and other hardware without removing the muzzle device from your barrel.

Installation is straightforward: standard 1/2-28 threading means it screws directly onto any AR-15 barrel with that pitch. No special tools, no guesswork. The toothed design is intentional engineering, not aesthetics—those vertical ports and internal baffle geometry work together to manage flash and recoil in a compact, reliable package. If you run an AR and shoot in variable light or want better muzzle control, this is a proven choice.

Frequently Asked Questions

Will this fit my AR-15?

Yes, if your barrel has 1/2-28 threading. This is the standard thread pitch for most AR-15 uppers and aftermarket barrels in .223/5.56. Simply thread it on—no special adapters needed.

What's the Plan-B HUB, and why should I care?

The Plan-B HUB is a modular mounting interface built into this flash hider. It allows you to attach Plan-B compatible suppressors, brakes, and other muzzle devices without unscrewing the Lamprey from your barrel. If you're running multiple rifles or like the flexibility to swap gear, it's a game-changer.

How much does this reduce muzzle flash?

The toothed four-tine design and internal baffle are engineered to reduce both flash intensity and duration compared to conventional flash hiders. Real-world results depend on ammunition, lighting, and barrel length, but the principle is proven: disrupting gas flow disrupts the visible signature.

Does this reduce recoil?

The internal baffle and port geometry help manage muzzle rise and felt recoil, improving control and follow-up shot speed. It's not a muzzle brake in the traditional sense, but the design delivers noticeable recoil reduction.
