Which Muzzle Device for AR Pistol

[donking]

I've seen lots of threads about how good the Battlecomp is, but what about for an AR Pistol?

Is the flaming pig or something else a better alternative for a 10" AR?

Better for what?

I'm running a standard A2 flashhider on mine with no problems.

Generally 10" AR pistols have less problems cycling than 7.5" AR pistols. This isn't a stead-fast rule, but essentially there is more burn time for the powder in a 10" and thus, more gasses available to cycle the bolt. The KX3 and Troy Claymore muzzle devices are there to basically help create more gas pressure in the 7.5" (or any AR pistol) to reliably cycle the bolt. As always YMMV.

I tried the Levang and the Claymore on my 7.5" Ar Pistol. In the end they both make the weapon very pleasant to shoot, but I found the Claymore's recoil was softer.

Use whichever one that makes the biggest flash when shooting at dusk!
AR pistols are fun and a real crowd pleaser.
A2 birdcage works for mine.

I have tried a few. The primary weapons CQB has my vote. It doesn't white out my NVG and doesnt give your buddies a concusion. They are proud of it, it ain't cheap.

What length barrel is on your AR pistol?

Which comps did you try?

Does this mean the 10" are well behaved enough to run a Battlecomp or PWS FSC?

Well, like I said, that is just kind of "generally speaking" - it depends on who built it, if they tuned the gas port at all and a handful of other factors. The point is, those types of muzzle devices (KX3, et al) will help any AR pistol cycle more reliably. You will probably be just fine with a Battlecomp, standar A2 flash hider or any other muzzle device though...

Better for what?

Reducing the recoil compared to the standard A2 birdcage.

I built a 7 inch .223 pistol and started with a standard birdcage flash hider. Loud, what!, Loud, say what!? The birdcage style muzzles allows the sound field to almost peal off your ears even under a good tight fitting set of noise canceling ears . I added a set of foam earplugs under the my ears I usually wore to keep the noise down. Anyone standing next to me got a concussion from being near the pistol and it's peach basket ball of flame it spued on each round.
I changed out the standard AR muzzle brake to a Noveske KX-3 flaming Pig and it made a HUGE differance in sound to the shooter and to anyone next to the pistol when being fired. Still has the flame throwing ability but the sound is pushed forward instead of all over. The KX-3 was desgigned for CQB style rifles so shooters inside buildings and hallways wouldn't deafen the team mates nearby or next to the operator.
As for making the pistol or shortbarrels work better in the gas system,I cannot say, my pistol has never had a problem with any ammo I have ever put thru it.
It has a Rock River national match trigger group and it will bump fire with the best of them. A full Beta C-Mag is emptied in under 10 seconds if I want to. The KX-3 made no difference in that ability either. I installed it to cut down on the side and rearward noise from the bang only. Currently it is a sfae queen pending a Form to ATF to make it a SBR

i'm currently running a pws fsc on my 11.5 barreled ar pistol and it works great.pending my form 4 getting approved i'll taking it off and selling it,then replacing it with a suppressor.

The KX-3 is much heavier/longer than the A2 and BC. Do you notice the weight/length difference?
