Barrel Length in the Airgun Industry

[OldVet]

Hey guys what is considered the barrel length in the Airgun Industry?
I always thought it was the part that was rifled. Does a shroud that is 5" longer than the actual rifled barrel count as barrel length , and what does 1/2 the threaded adapter have to with it?
My Guantlet I just bought needed to be cleaned of the factory pasty stuff in the barrel , so I pulled the 1/2 by 20 adapter off , and the 4 plastic baffles , and the spring. Then the shroud , and I measured the rifled part I call the barrel.
It was 23 1/2 inches long not the 28 1/4 I thought it was.
Now then I put the shroud back on without the baffles " Pellet Clippers" I call them , and the spring. I measured the 281/4" which was from the breach to the middle of the thread adapter. Ok am I wrong that the barrel is the rifled metal part , or does the shroud count as part of the barrel in the Umarex airgun Industry. OldVet wants to know.

The barrel is the barrel. It does the actual controlling of the projectile. Neither the shroud nor the muffler (hopefully) have any say-so in where the pellet goes.
Any other length is either shroud and or muffler (silencer, suppressor, damper, etc.) .

Seems that the last few years, people make up names, and or change names to suit themselves or groups, that actually have none, or little to do with reality. And the more that find that new word..."cool", will spread that new word, and so on, and so on.
Just like...I dare ANYONE...to swim "under water" !

I was lied to , and by Umarex saying the Guantlet has a 281/4" barrel.
It's 231/2" with a 5" of shroud. Don't even know why they did not lie about the other 1/4 inch as it measures 281/2. lol The thread protector was on so tight I had to use vise grips , and pliers to break it loose. Don't worry I wrapped a napkin around it and very lightly clamped the grips did not cause any damage to the thread protector.

Some barrels only have a short length of rifling towards the business end. The length of the rifling I'd call "rifled length" rather than "barrel length".

That's interesting. They sure do list the barrel length as 28.25". I've never seen anyone include shroud length before.

ADVERTISING > longer barrel usually "is thought of" as better long range precision . not necessarily so .

More like FALSE advertising. But yes that's the general thought that a longer barrel means more accurate which is also not true.

I try to have a calm demeanor, but I'm known to loose it sometimes , and I need to work on that , I'm ok now , but when I first figured it out I was pissed off , and felt cheated , and lied too. The damn barrel is 231/3 inches not 281/4 , and to me that is false advertising , and it just hurt my feelings real bad , because the barrel length played a big part in my decision to make the the purchase , and also due to my Zelos I was very happy with Umarex company , and now I feel cheated , and let down plus I don't trust them anymore. But I'm ok now lol. Edit: I forgot I added my Buckrail moderator to the Guantlet
, so my barrel is now 341/2 inches long.LOL.

Barrel length should be the length of the solid portion of the tube the pellets travel through. It doesn't have to be rifled and the pellets or bb's don't even need to be in contact with it, but it should be one continuous piece of metal. There have been guns made in the past with barrels that open up halfway down the bore so that the total length is very long but the pellets only contact the bore in the first few inches. I believe the intention was to provide a long sight radius while keeping the lock time/barrel time as short as possible. It was also quite common with defensive rifles in order to meet the 16" minimum barrel length requirement. They'd make the last 4" or so of the barrel some sort of permanently attached flash suppressor.

About the AR15 yes that is true as long as it was permanently attached it counted as barrel length. On a Guantlet the rifled barrel is covered by a shroud these are 2 separate things you can't say the Guantlet has a 281/4" barrel. It is 231/2" the shroud is 28.

I agree that what the gauntlet has isn’t a 28.25” barrel. It’s just a shroud over a shorter barrel. I was just trying to clarify that the barrel should be one continuous piece of metal, or perhaps one continuous laminate, but isn’t necessarily measured by the rifled portion or the portion that contacts the projectile.
