Tight Bore Barrels Diameter

scar 101

Hey lands just wondering about tight bore barrels diameters differrences between 6.01 and 6.03.i heard that 6.01 had better accuracy but less carry and 6.03 had mid accuracy and mid carry and 6.05 and alright accuracy and great carry is this true. what is the difference between these two barrels http://new.rsov.com/product.php?langId=1&currencyId=1&manufacturerId=10&prodId=3409&cateId=85 and http://new.rsov.com/product.php?langId=1&currencyId=1&manufacturerId=10&prodId=3168&cateId=85.
thanks scar.

I believe the tighter you go the more accuracy and fps you get due to more air lock behind the bb in the barrel. I myself use 6.02s was going to go for the 6.01 but heard they can get jams due been to tight.

Im currently using a 6.01 in an MP5K at the moment which i use as a side arm and i havent had any problems as of yet. Compared it to another one yesterday which had i think 6.04 and there was a noticable difference in range and accurarcy, not a lot, but definitly an improvement.

ok.... Carry? do you mean range? Whoever fed you that line was either having you on, or confused. There is no inverse relaltionship between accuracy and range. A tighter barrel, should, due to better air seal, and less vibration along the barrel, hence forth provide better range AND accuracy due to the increased stability of the bb. Thus is a positive correlation.

Wouldnt go 6.01 in an aeg, too easy to jam and a lot of bb brands are a bit larger... like bioval, g&g and ics bbs, and will deffinately jam. 6.03 is a nice mid ground between jamability and performance.

I believe you might be wrong on this the G&Gs and Ics are 5.95 are they not and therefore recommended for the tighter barrel.

The difference in range and accuracy between a 6.03 and a 6.01 tbb will be very small. Range wise you might only get an extra few feet. This is because the fps increase will be small therefore only pushing the bb a small distance further. The key to range is having a quality hop up unit and using quality heavier bb's. The difference in your accuracy will be the consistancy of the shots. BB's bouncing along the inner barrel before exiting so having a a narrower inner barrel reduces the gap between each bounce and leads to a narrower exit trajectory path. BB's dont exit the barrel exactly the same with each shot so by narrowing the exit path it leads to a more consistant shot than when using a 6.08 mm barrel. Therefore the exit path on a 6.01mm barrel is less than a 6.03mm so your shots will group closer but not a tremendous pile closer than a 6.03mm. If you are using a 6.01mm just make sure you use high quality bb's with a size and tolerance less than the barrel. If you want to increase range use heavier bb's (0.25g or even 0.28g). Its a misconception that lighter bb's will travel further as after a certain distance factors like wind, drag, etc, will affect the bb. An example is if you throw a lead ball that is exactly the same shape and shape as a plastic ball but is heavier the lead ball will travel further as its weight is able to act against the outside factors.

G&G bbs are larger, relatively, thus giving tightbore performance in a larger barrel... I've had to repair more jammed G&G bbs in tightbores during my time than any other bb brand. I said, in the post you quoted they arent a good idea for tightbores :P
plus bio bbs dont react with wet conditions well, and swell, thus jamming like bob marley with a truck full of Kali weed.

Excels are tiny for example, and perfect for a 6.01, roughly 5.91-2 iirc? (so small that guns like m11's cant hold them in the mags as they slip past the lips.

@FireKitten I'm not saying your lying just that I have been using G&Gs for a good while now in my 6.02 and 6.03 barrels and have never had a problem. In saying that I also use the Excels myself.

Firekitten

No, you said you thought I was wrong. Which is fair enough. I didn't think you called me a liar. I'm just going off my experience, not gospel truth. Afterall, I've not quite achived airsoft omnipotence yet... But im fairly close
I've seen a lot jam, you havent.... I think we're both right... And excels wouldnt jam, they are far too small... hence my m11 comment. If anything excell in a tightbore is like a larger bb in a standard barrel.... like buying a ferarri and putting olive oil in the fuel tank expecting it to run the same.

@Scar one thing I would like to mention is to check your FPS before and after changing your barrel as I had a raider fire at 324 fps +- with stock barrel and I change it out to a 6.02 and it went to 330 fps:eek: And the last thing you want is to turn up on a skirmish to be told you can't use it.

Firekitten

Its a matter of air seal... tightter barrel, less escapes, more propells the bb... seen a tightbore up fps as much as 20fps.... so yeah, hes right, watch out.

thanks Lads you've been very helpful with this but its for an aeg and a sniper by the way.

Firekitten

doesn't make a single difference. Method of propellant is identical, just operation of that prepelant differs (air)

The bolt action rifle and aeg have the same theory behind thier barrel and hop units. And in Ireland, the same fps, so no worries.

Ya well I think a aeg barrel would get more dirttier then a snipers barrel. Do aeg barrel fit in a snipers and would putting a pdi hop unit do anything more then just changing the bucking thanks.

Firekitten

PDI hop unit lets you take aeg BARRELS, and consiquentially, hop bucking and rubber. Advantageous? not really. Vsr hop is DAMN good as it is, if not one of the best. Spend your money on a nice tightbore, if its the maruzen style hop, dont bother either, those are gorgeous... infact i kept mine, dispite the upgrades, its hard to beat with a few tweaks.
