Here's a thought, if Illusion or someone else was still up to the task of testing these barrels.
Forget the idea of swapping springs firstly. All that is needed is a gas rifle in which you can swap barrels easily that has an external source and regulator. Fire off 10-20 shots through a chrony at the target and record the distance the BB deviated and its speed. Extrapolate that speed to energy. Repeat for different speeds and weights, then barrels. It would take maybe two or three days to measure all your data, and I would be more than willing to help out if this were to be conducted in the Ottawa area, or at the very least I have enough university lab experience to properly analyze the results and report on them. All this requires is the regulated gas receiver, a bunch of barrels, BBs, a chrony and an indoor spot to test. This will provide hard data for extrapolation to what springs can be used in what lengths of twist barrels to achieve the optimal grouping and the roll-off rate for those that want a bit more BB velocity. |

Anything over ~320 will start to lower accuracy, You would be better off buying a 6.01 tightbore

Why they then made this kind off barrels if they dont work in it?

Because there's a limit in Japan on how hard their guns can shoot. Outside of Japan, sniper rifles can benefit from far higher power, and the Twist barrel is far less useful than a tightbore in those cases.

yes, but if it shoots that extra bit further, wouldn't that be a point in favor of using a tightbore over a twist barrel?

What's the point of increasing range if it comes at the expense of accuracy? You want to be increasing effective range.

EDIT: in the end, im just going to order a DB custom 6.01mm inner barrel for the Marui M14 from Airsoft GI. supposed to have a 2-3" grouping at 25 yards with the hop-up turned off. Now that is impressive. Last edited by Donster; February 16th, 2008 at 14:26.. |

Not quite sure what the diametre is, but reports of a slight fps increase would suggest it's a little tighter than most stock barrels.
According to ILLusion, it won't help if you use a heavier BB. It's not so much a fps limitation these barrels have, but one of muzzle energy. Fps is simply usually more practical for describing them than Joules.

Does anyone know how tight this inner barrel is?

no we dont have an exact measurment. dont think of this as a tightbore barrel. this barrel is in a class of its own. from reading about this, id get this barrel for pistols and stock guns that you keep as backup in case your main gun fails. at least then you can hit what you shoot at.
P.S: fill out your profile and location and age. there are many bilingual people on these forums. perhaps they speak the same language as you. |

Not if your gun can't (or is limited to) shoot over 1J. Think pistols, stock guns and AEPs. If you're looking to install this in to your bolt action sniper rifle, I surely do hope you live in Japan...

fair enough. but i am talking about canadian airsoft, not japans. in japan, this barrel would be the best choice IMO, but here, i think a DB Custom 6.01mm barrel would be the best. you get both accuracy, range and power (at least if the site is not falsifying their data)
