Lantac Dragon Muzzle Brake


Great piece! I have one installed on my AR10, and it helped a lot with the muzzle rise and recoil. I'm pretty sure it'll do the same or better with my AR15.

A great muzzle break! Very pleased with my purchase. Outstanding service from Primary Arms.Thanks

Worth the money!


absolutely amazing! Just got my first AR and am learning about the weapon system. If you want a quality part don't even hesitate about buying this! WORTH IT! I can't wait to shoot it again! Makes the shooting experience way better with almost no recoil and muzzle rise its crazy

Lantac Dragon Review


Absolutely my favorite comp on the market. Keeps muzzle level for very quick follow up shots. You wont make friends on the range due to the noise, but that's life with most great comps. As Always Primary Arms has the best prices and quickest shipping.

Great Muzzle Brake but......


Although the Lantac Dragon "Zero Recoil" is a well made product when screwing it on the end of my Keltec SU-16C the ports didn't line up. According to the directions the venting ports are supposed to be on top when tightened... this was not the case. I hate to send it back because it is a a good muzzle brake so I will use it on another rifle instead.

Amazing brake! Was at the indoor range tonight and boy is this thing loud. Had clouds of smoke blasting left and right. Anybody near you can fell the concussion, my friends glasses was shaking. Product does what it says, i highly recommend it.



Amazing brake, i mean Amazing...

Best Muzzle Brake I've bought, hands down. Thanks to Primary Arms for speedy delivery and great customer service!

Bought this break when it was on sale. Shipping was super fast. The break is unbelievable. Doesn't reach "zero" recoil, but the recoil is almost completely gone. Well worth every dime.

Oh man!


Didn't realize how big of a different a muzzle break makes on a AR15...but it does! Virtually no jump at all. It is louder for sure but it creates such a speedy platform for continuous fire.
