A muzzle device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons.
Its primary intent is to reduce muzzle flash and the chances that the shooter will be blinded in low-light shooting conditions. It is only a minor secondary benefit if a flash suppressor reduces the intensity of the flash visible to those down range.

No is the correct answer for a flash-suppressor. All but long distance target ARs seem to come with a flash suppressor from the factory, like the cigarette lighter in a new car. It's kind of expected because that's what we've always done.
For a muzzle-break the answers is "it depends." Do you want to reduce recoil? Most experienced shooters know that there's very little recoil from the standard AR15 platform, but more so with the AR10 platform in 308 Win.
I personally have no need for a flash-suppressor on any AR platform. The only down range victims would be zombies, and since they're already dead, the flash wouldn't likely bother them. But here's why I always have a muzzle-break.
Part of the recoil process is a rise in the muzzle. May be slight, may not be noticeable, but may also be significant.; just depends on the caliber. Regardless of the rise, the muzzle-break helps keep the front of the muzzle down and closer to where you need to be for your next shot.
Think about how long it takes to get your sight-picture back on your target after a shot. Not a big deal for an afternoon plink-off, but when your trying to hit the next coyote at 250 yards in low light, you need your sights lined up again quickly for a second shot. Even more so with optics.
SPARTAN AR is not going to ship a threaded-barreled rifle without a flash-suppressor, simply to avoid rocking the boat of tradition. But, you can always upgrade to a muzzle-break or go with a standard thread-protector. installed.
Hollywood has done a great job making the theatre crowd think a suppressed firearm is "silent," aka "a silencer." You slink into a crack dealer's hideaway, tick-tick-tick away the bad dudes with your "Nine", take the loot, then sneak away into the fog. By the way, shooting up a whole group of "homies" is now called "wet'n 'em down,"; who knew?
Well, nothing could be further from the truth. As the name implies, the noise is simply suppressed (reduced). So, when shopping for a suppressor, determine the decibel level reduction, then try to get a reference sound of the same decibel level and try to determine just how little sound it is going to make. Anything less than your wife's "getting angry voice" should be fine. A "really angry wife voice" is much loader than a suppressor.
I was once in love with my custom sniper style 308s; capable of placing 1 in 5 shots down the breach end of a 30-06 barrel at 100 yards, mounted securely on a $1500 solid mounted and leveled bench rest, pneumatic trigger actuator, topped with a $4000 Night Force scope, firing 168-gr boat-tails (super-high quality hand loads).
Those days and the bragging are over now, but the reason I placed a suppressor on the end was simple; I didn't have to keep taking off my ear protection to talk to my spotter about the next round. The sound was akin to shooting a 22 LR, so it wasn't enough to have to keep the hearing protection on.
I have no experience with any other caliber, so there's not much more I can say about suppressors.
I have a question that no one has ever been able to answer, and I'll give anyone with the correct answer an "ata-boy." I believe a physicist might be able to answer it, but the only ones I know are make-believe on the Big-Bang tv show.
Let's say I have a muzzle-break on my 300 Win Mag. Assuming my other barrels have the same diameter and pitch, it will work on any 30 caliber rifle (308, 30-06, 7.62x39, 300 BO, …) We know that to be true; no physicist required.
But, what if I want to install it on a smaller caliber rifle, like a 223, 6.5, 7mm, etc. I know I can install it, so the question is, will be effective? On the one-hand I seem to think there would be no degradation in accuracy, velocity, trajectory, etc., since the bullet is just riding though a bigger hole. But on the other-hand, perhaps the over-sized hole will make gasses swirl crazily and erratically (or is that erotically) around the bullet as it passes through and will degrade the performance.
I guess I could rob my retirement account and do a lot of field experiments, but at the end of the day I really don't care that much. I can die without knowing and I'll still feel good about my life. Any thoughts from the p-nut gallery?
As we talk about physicists, we're really talking about geniuses. Many of us stand in awe of their mental prowess and intellectual abilities. But before you get to carried away and become overly impressed, remember that these people are just geniuses in one particular area. It could be physics, economics, astronomy, strategy, chemistry, and so on. And for a lesson in such, let us recall the greatest physics genius of our time; Stephen Hawkins. Although he authored some of the greatest theories in physics and quantum mechanics, he still fully believed in global warming, which just goes to show he was a "village idiot" outside of his field of expertise. A lot of people think I'm a genius but those are usually really stupid people, so I still go to bed feeling kind of dumb.
And why can't you win a climate change argument with a liberal?
