hello asf I just found this on asgi, it says it is made by G&G, but it is only $170

what is it? http://www.airsoftgi.com/product_info.php?products_id=4587

It's part of g&g's "sportline" series, which have plastic bodies and (I think) slightly different internal parts.

Well, it is the same price as the other G&G M4, so it could be another one. But this one has the USMC logo where the G&G trademarks were on the older one.

ya it looks like the G&G sportline, but with the usmc logo, I am not sure about the internals though

Sportlines have the same exact insides as a normal G&G, minus the tightbore barrel. And it does look to be a Sportline G&G.

it now is $140... I wonder if it is a sportline with wierd internals..

here is a bit of a better description and a video surrouding these guns

Interesting... so is zinc a decent metal for construction of an AEG body? All I know zinc from is vitamin supplements.

The body itself is not made from zinc, it is made from a nylon fiber. The outer barrel/rest of the metal parts are zinc.

Ah, my mistake.

I don't recommend licking your barrel to get your daily dose of vitamins.

But it sounds like these are just G&G Sportlines made out of slightly different materials. Not much of a difference in my eyes.

why does it shoot only 330 fps/ doesnt the regular sportlines and prolines shoot around 360

Well at leat it has decent markings on the gun, I don't have to highlight them myself.

WHAT tightbore barrel



It will most likely shoot the same FPS as all the other G&Gs. Companies don't have much variety in stock FPS, pretty much all their models have the same spring. JGs ahoort 360-380, TMs shoot 280, CAs shoot 330, KWAs shoot 400, G&Gs shoot 350-360, etc.

Well, Cymas shoot from 280 to 470, but they are an exception.

The stock tightbore, the 6.04 that you will probably want to replace anyway, eventually?

In my eyes, CYMA is a misfit. They have a few good models, yeah, but that's it. They don't have enough models out on the market to warrant being grouped into any category.

The stock barrel, you mean? read my sig...

They may not be high quality, but they are still tightbores

What defines a tightbore, pray tell? A barrel with high quality control, yes? Then how can you categorize G&G stock barrels and "tightbores" if they're not high quality?

the term is just an advertising gimmick, and means nothing in terms of additional performance.

It is funny how the barrel look so shiny...and the review does not talk about what the barrel is made of(just said metalworks... which could mean the front sight).

And a regular G&G plastica is $170, why is this one $140 and actually have good markings???

Probably has a plastic barrel...

Could be the paint they used.

Gee, mister hydra, I always thought that they were called tightbores because the bore was tighter than the standard 6.08 barrels. Smaller diameter bore would be tighter around the BB, that's my guess at the etymology. The real one would likely be slightly difficult to find, given that I'm guessing it was a translation of the Japanese, and they sometimes have odd logic behind naming.

It might not be high quality, but it is still tighter than the standard 6.08, therefore it is a tightbore. You could make a 6.01 barrel that is about as smooth as 40-grit sandpaper, and it would still technically be a tightbore, it would just also qualify as a POS.

The outer barrel on this one is zinc, rather than aluminum, same with the buffer tube (I assume, that is what it sounds like they were describing, they didn't use the term), that could be why it is lower price. Anyone have experience with zinc to know if it will stand up to the stresses put on an airsoft gun?

the inner barrel on the guays, while not being very high quality still makes a difference than a regular barell. I will show you proof with a video possibly in the future. the barells aren't that good but still make it more accurate.

Yeah, I was wrong.

This one is so cheap is because the barrel is made from zinc alloy(potmetal) instead of aluminum on normal Plastica.

But if you do not care about the external, go ahead and get it.

The caliber has to be at or under 6.05mm...
The word "tightbore" has nothing to do with QC and everything to do with how small the caliber of the barrel is.

If I were you, I would leave the attitude elsewhere.

If you want to be nit-picky, then "tight" is a relative term. A 6.08 can be defined as a tightbore in relation to crappy barrel, I.e. one made by well or firepower. If you look at it that way, then JGs come with "stock tigthbores."

Who says 6.08 is standard, anyway? Why don't we just call 6.10 "standard" and call 6.0 a "tightbore?"

If you want to be realistic, tightbores are barrels that increase performance. forget about technicalities, I'm talking about PERFORMANCE, which is all that matters.



Well, what's your definition of a regular barrel? More accurate than what? If it's not very high quality, how can you guys claim that G&G has tightbores, which are supposed to increase performance?

a video would be nice, actually. Or maybe some actual tool that measures the bore AND consistency of the barrel.



I respectfully disagree. The term has everything to do with QC and nothing to do with the caliber of the barrel. A well-made 6.08 barrel will out-shoot a crappy 6.03, thus earning the title of "tightbore." When we say tight, it is assumed that the bore is the same throughout the entire length of the barrel. In reality, the space between the BB and the barrel is so small, why don't we just call 6.08 tight? After all, there's only an average of one/tenth of a MILLIMETER of space. That's tight to me. A low-quality barrel will fluctuate in inner diameter, thus resulting in inconsistent shots, and decreased performance. If the bore changes, and at certain points is even bigger in ID than a "non-tightbore", it's not "tight" anymore, is it?

I just want to mention that this one does not have a functional charging handle, so if you pull it, the dust cover does not open, so I'm guessing you have to manually open it to get to the hop-up

A barrel with a smaller bore than the usual norm of 6.08. And it does improve performance.

If anybody else wants to say somthing about it or tell me off, do it in a pm so I can just block you and forget about it.

Thanks,

Forrest M.

Just because a barrel is marketed as having a smaller bore does NOT mean it improves performance. the tolerance of a barrel is much more important than the average bore, which is what products are advertised with.

Hydra, I want to preface this by saying that from all of the threads I have read, you tend to be a good poster, knowledgeable, coherent, not a jerk, but on this, I disagree with you completely. 6.08 is standard, as far as I know, because that is what TM used and uses, and the AEG world has been pretty well built around TM. If they had made 6.12s (like I believe AGM's M14 had) standard, anything tighter than that would be a tightbore, regardless of quality. A high quality 6.08 could outshoot a crappy tightbore, but the 6.08 still wouldn't be a tightbore. Tightbore is different than high quality, they just are generally considered to go hand in hand, whether that is true or not.

edit: Don't disagree with your post right before this one, you snuck that one in on me.

second edit: You know, unless someone finds the origin of tightbore, I think this is going to end up being a semantics debate.

I think so. I think of tightbores in terms of pure improvements in performance, which admittedly, might be a different perspective than most people. I just think that a product's performance is much more important than what marketing term is used in conjunction with the item.

Still, I would like to have someone show some hard evidence that G&G stock "tightbores" perform better than other stock barrels, to back up the claim that G&Gs have better stock accuracy because of their "tightbores." It would be interesting to see someone run a test comparing the different stock barrels.

so, someone should get 2 of the same guns, with the same oarts, such as hopup, and GB, and one would have the G&G barrel, and the other should have say, a E1 6.08mm barrel.

then shoot in a controlled enviornment, such as an indoor gun range, and record the findings

"it says it is made by G&G, but it is only $170"

sportline variant

So does anyone know which is better, zinc or aluminium?

I think zinc is heavier and cheaper than aluminium, reason why this CM cost $30 less than the standard m4 Plastica.

+1 Materials and Finish. This is what the major difference is from MOST guns, and their respective price points.


Zinc is a nice metal, When it is mixed correctly into an alloy. Same with Aluminum.


Nodaisho : The debate you started with Hyrdalover over a tightbore was pointless and RUDE. Hydra was correct in meaning that a "Tightbore" barrel in all of it's references in the world of airsoft is in relation to improvement of that of a 'known stock" 6.08 bore barrel.

Now I will NOT argue with either of you 2 of the "differences" of a tightbore, from manufacturer to manufacturer. Other then to say Hydra IS correct. Tolerance of machining is MUCH more important then "advertised" bore. I've seen stock 6.08 TM barrels out shoot MANY of the 6.04 "factory" tightbores from G&G and Cyma respectively. Yet I have seen many 6.04 "after market" tightbore's from Madbull, Systema, out shoot the TM "stock" barrel.

It all comes down to machining tolerance and material finish.

Tightbore = smaller bore than 6.08. Simple as that

IF two inner barrels are made with the same qc, and one is 6.08 and the other is 6.01, and there is no other difference, the 6.01 should obviously outperform the other one. However, the idea of a tb has been distorted with low quality barrels with small bores.

And thanks hydra for the cm review it made me buy it.


Heh but I put a tb in it....
