What's the ideal muzzle device on a 10.5" AR pistol?

Easy.
Suppressor.

The Sons of Liberty 5.56 Nox flash suppressor looks like a winner too, and you can get one for a suppressor as well.

Though I have not yet tested it on my pistols (but will soon), my current hypothesis is that a linear compensator will be more useful in a range/home defense role by directing at least a portion of the blast, flash and noise downrange. In a HD situation I'd rather my weapon disorient the bad guy more than myself. If I was in a night time fire fight scenario flash would become a bigger issue I would think. Just my unproven logic. I just don't see value in a brake when running 5.56 or 9mm and a flash hider seems unnecessary in my non-operator style of plate and paper intimidation.
I do actually hit them occasionally.

Update: Threw a Kaw Valley Linear Comp on an 8" pistol yesterday and ran some American Eagle .223 and a mag of my hot reloads. I have no testing apparatus to get decibel numbers but the volume was maybe slightly less sharp, but the concussive blast was noticeably diminished.

All of my SBR's are equipped with suppressors.

What role are you planning for it's primary use? Range toy, home defense, etc?

 

[powermad]

I run a KVP linear comp on my 8" AR9.
The only time I can see the fireball is at the indoor range, and it's not that distracting.
I like it much better than the A2 style FH that I started with.

Range toy also configured for home defense, would probably be the best answer.

I have a 16" FN CHF that I've swapped a scope onto and this 10.5" build is going to be my "main" gun. XPS 2-0 equipped for close range, etc.

 

[Helocat]

Suppressor for the win, hands down.

 

[JustSomeGuy]

If it's going to do any home defense duties, your best bet is to go with a suppressor unless you plan on everyone in the house doubling up on hearing protection before you fire.

I just have an A2 flash hider on my 10.5" pistol and I don't see a huge amount of muzzle flash. I did some testing with Speer JSP as well but maybe it loaded with reduced flash powder?

I'm not done with the the build yet but I'll be using a linear comp on my 12.5", specifically the BRT Covert Comp.

YHM Turbo suppressor
Its reasonably priced and comes with a QD muzzle device/muzzle brake. And it works.

My 10.5" was a fire breathing monster so I put this on it and it has no visible flash now. I have not shot it in pitch black yet but it does well at twilight.

if it's what you're going to actually grab to defend your home with, put a can on it. A 10.5" will hurt indoors.

 

[draza]

In most cases obv a suppressor but a little more realistic answer would def be a flash hider and a good one at that.
Flash can too maybe?

 

[308]

Best IMO opinion is this, and I have tried many.
Obviously for a 762x39, but variations are available for the 1/2-28 AR bbl. It will all but eliminate the fireball and direct the blast/sound forward. In fact, you can buy a thread adapter which will allow one to use the original Bulgarian hider on the AR. I did that because I had some on the bone pile.

If you run a suppressor, make sure that you get the cycling right.
You can do it with:
1) adjustable gas block.
2) combination of weight/springs
3) both of the above.

What you don't want is too much gas back causing the BCG to either not eject properly.

My 300Blackout SBRs (12" barrel) both have cans.
My 5.56 AR pistol (10.5" barrel) does not, as I have had issues with it and the suppressor (AAC M4-2000) and many many FTEj and just haven't gotten to fixing the gas block.

So far I run a Smith Vortex on everything, including the new 5.56 10.5" pistol I just put together.

Agreed that a CAN would be ideal for home defense, but then you are just making it longer, and if I was planning on a CAN I'd be using 300 BO and an adjustable gas block.

For now I'm sticking with the Smith since it KILLS the flash and will grab my noise cancelling ear protection if I'm not going for a pistol.

IMO you don't need a brake or compensator for 5.56. Honestly can't tell between a flash hider and a brake on this mild round.

A brake from an M82A1, obviously

I'll check that out. I have a Stag Arms 3G in the parts bin and it comes with the standard birdcage. I'll give it a few rounds before making a change, but I'm pretty sure that I'll end up wanting something to push more of the gas forward.

Using a Geissele .750" Super Gas Block, so no go on adjustments with this build

I want something like that for a frankenstien cyberpunk G19 I'm building
