Threaded or non threaded Barrel?

[DarthVader]

This might sound like a stupid question but what is the difference between a Threaded Barrel vs a Non Threaded Barrel?

Is there any benefit of having or not having a threaded barrel.?

The only thing that I am of aware of to having a threaded barrel is for using a muzzle brake,Compensator,flash hider or silencer..

The only thing that I do know is that depending on what type you use they actually reduce recoil and muzzle climb but is this the only thing that they do..

So basically I like to know if you could have a muzzle brake,flash hider or Compensator would you buy a rifle with a threaded barrel or would you go with a non threaded barrel.?

Practically speaking I don't believe having threaded or non threaded barrel makes much difference to an average shooter after gun is zeroed with whatever device you put on it. Theoretically a non threaded barrel of same size materials etc with crown will be more accurate than threaded barrel with device meaning the device will cause the POI to shift other things being equal. Again in practical terms this doesnt make much difference to average shooter once the gun is zeroed. However some devices will make perceived sound louder and felt percussion stronger esp to the guy next to you at range so that may be an issue to consider depending on where you intend to shoot. Keep in mind threaded barrels with devices are so-called "evil features" under current NY law so it's a no-go with a semi auto and detachable mag. If you're building a NY compliant AR15 a threaded barrel will either need to be capped and pinned or the mag will need to be made to be non-detachable (note I'm not aware of any official guidance or case law establishing what exactly this entails and this is certainly not legal advice). Personally I'd go with a non threaded barrel if you intend to make a NY compliant AR with detachable mag (No pistol grip, Thumb hole or collapsible stock either). Believe varmint barrels generally are non-threaded and sometimes beefier than standard barrels. If you decided to go with threaded I believe Mek would suggest 5/8" threads over 1/2" but make sure whatever device you intend to put on it is compatible (to repeat not for semi autos with detachable mag within NYS). Good luck.

A little 5.56/.223 peashooter does NOT need a muzzle brake or compensator, anybody that is recoil sensitive to such a small caliber should probably go back to airsoft guns.

What I found under a muzzle brake was a fair amount of built up carbon on the crown after a few shooting sessions. I believe eventually the built up carbon could impair accuracy. If I was going for a muzzle device I would want one through which the crown was accessible for cleaning or was easily removable for the same reason.

Depends on the caliber. Having the threads gives you the option to add a muzzle device if you want to. If you don't want a muzzle device, just use a thread protector. Unless you're feeling the need to reduce muzzle rise or recoil, the most accurate setup is probably going to be no muzzle device. Any kind of muzzle device complicates the cleaning process and there will be carbon buildup at muzzle you'll have a hard time eliminating.

It depends on what you are going to do with those threads.
For small calibers is not really needed on average reduction of recoil is not justified by the increase of noise and maintenance.
It also depends on the overall weight of the rifle plus the weight of the load along with geometry of the gun, ergonomics and other factors that are going
to determine the amount of perceived recoil and the actual impact to the shooter.
If you choose a brake make sure you get a light one with one or two ample wide open baffles that is the best thing. Also if the crown is flush or even
a tad above with the baffle being wide enough cleaning is not not a problem w/o ever taking the device off.
Also one might have a barrel threaded to install a custom sight post with the widest possible sight ratio. The advantage of a threaded sight block vs.
a clamped or pinned is that it can be a lot lighter and very strong.
There are other possible uses for the threaded muzzle but also make sure you are ok in terms of fuac - ny.
Never buy a rifle wiht 1/2" threads at the muzzle unless is a 204 or .17 bore. They are too small even for the 223 remington. I know they are popular
but that was a design mistake like a few others flaws found in ARs, AKs and bolt action.
Instead look for makers that provide the 5/8 standard for those calibers unless is a 338 then it should be 3/4x24"

[Meketrefe]

BTW you can have a muzzle brake w/o a threaded barrel.
In fact the brake or compensator do not have to touch the barrel like for example if they are part of a shroud attached to the handguard.
Those are FUAC approved since the barrel would not have threads and will not touch the barrel.
Would probably have to find a shroud from a classic gun and have an adapter for whatever handguard you use that ideally should be
of the tube type to make it easier in a modern gun like an AR. machining is simple. The AK or Mini would be more complicated
and a tad awkward. Bolt action would be fine if you use a tube chasis but then there is no point on a shroud when you can have
a nice std. thread.

I don't think that is correct, PL 265.22(vi) states:

a flash suppressor, muzzle break, muzzle compensator, or threaded barrel designed to accommodate a flash suppressor, muzzle break, or muzzle compensator

(Notwithstanding "Brake" vs "Break", dumb f's, lol)

Ok everyone to give you a idea off what I am looking at getting here is the AR-15 that has a fixed magazine making the AR-15 legal to own NY with a muzzle device, which is a CQB Compensator,the AR-15 also will have a Pistol grip and a adjustable stock,I have been in contact with DSI about this AR-15 and it is perfectly legal to own with all these features because it has a fixed magazine,the AR-15 does not even have a bullet button..

Here is a picture of the AR-15 and specs that I am looking at getting..I could also go with another AR-15 that has a detachable magazine which looks almost like the first one but with a Thordsen Enhanced Buffer Tube Cover w/ QD Sling Sockets - FDE

That first one is cool haven't seen a lower receiver with no mag release before. Don't get me wrong it sucks that we can't own the most common MSR in the country but it is cool the company made a compliant rifle for NY.

You will have none of those because the shroud will do that. No threads on the barrel. So FUAC doesn't apply.

[Meketrefe]

Why do you want to spend the money on a AR15 that doesn't have a detachable magazine?
IMO it defeats the main purpose of having an autoloader with a detachable magazine.

You will be shooting faster and more accurately with a bolt action with a detachable magazine system.
just need to work a bit on technique but otherwise an AR with a fixed magazine is a waste.

[Cgrutt]

Law reads muzzle break (sp), muzzle compensator OR (emphasis added) threaded barrel...

or are you saying there is no brake/compensator but the shroud performs same function?

Meke that is true that is why I might go with the 2nd picture I posted as it will have a detachable magazine,to be honest I just want another AR-15 no matter what, the other thing is if the Unsafeact would ever be repealed I can always change out the stock to have a normal AR-15..All I can say is at some point in time this Unsafe act will not last for ever because we all know that Coumo will not be the Governor for ever in NY..

Clearing a brass over bolt jam sucks azz when you can't drop the mag.....
