Thoughts on muzzle device under the silencer…

[BillyBeards]

Does anyone have any thought on if the muzzle device the silencer is mounted to has any effects?

I have a Dead Air Sandman S that I use on multiple rifles that uses the Keymo mount. I’m curious if anyone thinks that having a brake vs. a 3 prong flash hider vs. nothing will have an effect.

I don’t think it matters but this new upper will have an 18” Proof barrel.

Thanks

I- personally- don’t think it matters, but I have brakes under my suppressors; because that is what I want in the event that I am shooting without a suppressor. But, there is a school of thought that says that mounts use up internal volume of the suppressor, reducing their effectiveness.

I am also leaning towards a brake on this one for the same reason but if there is evidence that it’s detrimental I’ll rethink it.

Run em both ways, makes no nevermind when the suppressor is attached

I don’t think that there is any difference in accuracy or sound reduction between the two types of muzzle devices.
I run flash suppressors on nearly all of my guns because that’s what I want if I am shooting without the can.
The only exception is my 10.3” 5.56 mm AR.
I have a brake mounted on that one because it *may* help to reduce wear on the first baffle in the can.
It is really obnoxious without the suppressor mounted. I never shoot it unsuppressed.

Equal gas pressure release has, IME, given better precision. I’ve run brakes, a2’s, and 3 or 4 prong flash hiders and I’ve always gotten better groups with muzzle devices that equallaterally disperse the gasses at the muzzle. Sometimes it’s a minuscule difference and sometimes it’s significant. Maybe there’s nothing to it. It just always seems to work that way.

A2’s and brakes with ports at the top seem to be the worst.
