The bullet gets forced into the barrel and has to seal against the side walls. The difference between the barrel and the bullet is miniscule. With the bullet being just a tiny bit bigger. they call the 5.56 a .223 generally speaking also but when you buy bullets to reload for it the bullets you buy are .224. This was just a general answer but I will let someone else get more detailed. Oh and yes it is normal

I infer from your question that you took a round of ammunition, tip first, and tried to insert it into the muzzle.
Yes. This is normal. The projectile forms a tight seal to the barrel. Propellant combustion produces the pressure needed to push the projectile down the barrel, all the way engaging the rifling, spinning the projectile.
If you have a handgun and try the same with your pistol ammunition, it will be the same.

NY is your propblem
You already figured out the answer to you question but I have to say outlawing a flash hinder is ridiculous. All it does is help keep gas from the barrel blowing towards the shooter. They tried that in co and the politicians had to get lectured on firearms tech. Some thought you threw mags away after shooting so by outlawing our 30 rd mags they would magically disappear. Ny is the worst when it comes to this.

The flash suppressor has little, if anything, to do with directing gas away from the shooter. A barrel, left alone, will blow the gas out and away from the shooter every time....don't need to add anything to it to make that happen. The flash suppressor's purpose is to reduce the flash signature at the end of the barrel which helps preserve the shooter's night vision during low or no light shooting conditions. Selection of ammunition (or powder if you are a reloader) that has a low flash signature will work hand in hand with the flash suppressor for the most effective reduction overall.

A flash suppressor does direct gas in a specific direction. It can help control muzzle flip and manage recoil towards or away from the shooter depending on its application. It also helps protect the end of the barrel. Hiding your flash signature is just one of its functions.

Flash suppressors are not muzzle brakes. They vent gas out the sides at 90deg. to the barrel to reduce apparent flash to the shooter. Muzzle brakes use the gas vented backwards to counter recoil and control muzzle rise but mainly to make the gun less punishing to the shooter ergo a Barrett .50 BMG. Using a brake also directs the noise sideways and back and can be quite annoying to shooters to your side. Not so with a suppressor. Also, why would you want to increase recoil?

You are correct,they can be two different things. I was referring to S&Ws flash hider(in there words) that's currently on my moe mid. It does both.I forgot that they use a birdcage on production rifles as well. People are mounting reverse brakes on their 15-22s w/bump fire stocks in order to increase recoil.

No problem.
With the lack of .22 I want my 15-22 to shoot slower

I got curious about the terminology so I looked up flash hider,everything comes back to flash suppressor. If S&W is marketing a flash hider that does both,then what's the proper terminology? Or can a flash suppressor do more than hide flash? I also looked up muzzle break. It said nothing about suppressing flash. It did say that they are either fitted to or permanently attached to the muzzle and are usually for lager caliber firearms. Dosen't really make me think of a threaded 5.56 barrel. I think S&W got it right,its a flash hider/suppressor that also directs gases and manages recoil. Opinions?

RD,
From my understanding a flash suppressor's (hider) only purpose is to reduce visible flash. The A2 flash hider really doesn't suppress all the flash. The Smith Vortex flash suppressor is a better example. It doesn't redirect gasses to the sides or back. It's designed to create turbulence which causes the hot gasses not to ignite. Since the majority of the combustion gas is moving forward, the flash suppressor does not counteract the equal and opposite rearward force.

^ Different flash suppressors shot at night. Amusingly the dudes try to sound "tactical".
A muzzle brake (compensator) purpose is to redirect the hot combustion gasses to the sides. If the gas isn't all exiting forward, there is no equal & opposite reward force. It does nothing to stop the hot combustion gasses from igniting when leaving the barrel.
There are hybrid flash suppressors / muzzle brakes. The suppress some flash and reduce some recoil. A portion of the gasses still moves forward. A portion of the gasses is redirected upwards or to the sides. They are a compromise. IMO, pointless.

I understand the differences between the two. S&W claims that the flash hider on my moe mid and m&p10 reduces flash signature while directing the gasses away from the shooter.Why not just say it reduces fs? I guess its a hybrid of some sort. I was wondering if it performs both tasks how do you determine what it is called? If its directing gasses at all, would that make it a muzzle break? That video was pretty funny.
