Questions & Answers
Will it fit .223Ruger Ranch riffle?

It will fit any barrels with 1/2X28 threading.

by Garett, Verified Owner, May 10, 2019
What is the length of the muzzle device? If pin and welded to a 13.7 barrel is it possible to have an overall length of at least 16 inches? Expert Answer

The muzzle devices overall length is 2.57" and with the threading, it will most likely be slightly under 16".

Absolute favorite ASR muzzle brake by buck, Verified Owner, April 22, 2019
This thing performs and looks great. Shoots flat as my HS girlfriend. Great lock up with all SilencerCo ASR devices. Comes with shims so you can appropriately time it correctly. Does not come with Rocksett like SiCo ASR muzzle devices do.

Neat alternative to ASR by Nick, June 29, 2020
I like the additional upward porting. It helps mitigate recoil on a 556 rifle more so than the standard war brake from silencerco. It looks much nicer than the standard silencerco brake and has a much more aggressive shape. I’m satisfied.

great follow up shots by edtx, Verified Owner, September 17, 2021
I’ve bought two of these and am really really happy. It helps with barrel rise. If you’re into big balls of flame, this is also your brake. On the obnoxious side, I have been moved to the end of indoor gun ranges cause of the concussion and flash. ...

Looks @ works great! by WR, Verified Owner, August 11, 2021
Love this thing! I will be buying a few more. Great machining. Looks and works great! I just wish they had more to choose from. Everything I’ve purchased from Lantac has been top notch. Lantac has not let me down.

Solid muzzle brake by Foo, March 15, 2022
This is a quality up grade to any bird cage or common muzzle device. It reduces felt recoil and helps with follow up shots and reacquiring your target, by keeping you rifle flatter. The threads allow suppressor attachment with ease. I have this devic...

Product Info for LANTAC Dragon SilencerCo ASR .223/5.56 Muzzle Brake

LANTAC DGN556B-ASR Dragon Advanced Muzzle Brake with SilencerCo ASR Quick Mount Suppressor Adapter.image

The DGN556B-ASR is precision machined, hardened to 48Rc and nitride finished for enhanced corrosion resistance.

It features our patented gas handling system that reduces muzzle rise and recoil to zero, meaning that the only recoil felt by the shooter is from the movement of the carrier and buffer within the buffer tube.

Its unique Short Energy Pulse system reduces length of recoil so that repeating shot energy cannot overlap and knock the shooter off target.

Full auto fire is possible with massively reduced recoil and muzzle climb, meaning that all shots fall on target.

With the addition of the SilencerCo ASR quick mount system it is now possible to mount the SilencerCo Saker, Omega Suppressors and the Blast Shield.
