Recently I was reviewing Japanese bulletin boards and blogs on Airsoft and noticed something interesting regarding what the Airsofters in that country think about replacement inner barrels, esp., PDI and Laylax/Prometheus.

The prevailing opinion about these premium barrels appears to be: "They are good, but not that good."

Quite a few comments were found comparing the Marui stock brass barrels with the PDI and/or Prometheus barrels, and the most common was: "Did not notice any difference." In a few (likely unscientific) tests performed by bloggers, the Marui stock barrels in fact were found to perform better than PDI and/or Prometheus, notably in grouping.

It was not easy to find reviews from non-Marui users, since just about every Airsofter in Japan seems to own a Marui. I saw some Maruzen owners, however, and their feelings regarding replacement barrels pretty much echoed those of Marui users.

Please do note that these user comments were generally about the brands, not necessarily about particular types of barrels such as IDs and subtypes like EG, Raven, etc., although I did not see any particular enthusiasm for the higher-priced subtypes, either. When I did find something about high-end barrel models, it was usually "Should not have spent that kind of money." This included Orga.

Rather amazingly, the stock Marui barrels are in such high demand in Japan that used Marui barrels are sometimes auctioned off at higher prices than brand-new PDI and Prometheus barrels. (Marui does not sell its barrels as aftermarket parts in Japan and only provides them as service parts when performed by themselves)

I can theorize as to why the appreciation for those premium barrels is more muted in Japan than elsewhere. But I will leave such discussion for some other time.
 
AFAIK Japan have 1J limit for their airsoft guns, so maybe this is thing.
 
I don't have any expertise with Japanese airsoft, but I've watched a bunch of Japanese airsoft videos... the guns just don't seem modified like American or European ones. I've always assumed it was the 1J limit that sad1ce mentions that keeps people from modifying their guns.

Also, the Japanese airsoft fields in the videos look *tiny*. Lots of movement and CQB, little suppression, very little long-range shooting. In those conditions, who cares what barrel you have?

Yes, the 1J (actually, 0.989J) limit probably plays a part because increase in the muzzle velocity from tighbore barrels can be a bad thing over there, potentially getting you into serious trouble with the law (1 year in prison). As a matter of fact, practically any Japanese joint that sells not just inner barrels but also any Airsoft part puts out a disclaimer that the user is responsible for making sure that the J limit is not exceeded after any modification.

But many Japanese users point out that they are not that impressed with the aftermarket premium barrels in terms of the improvement in accuracy and distance, either. Are these necessarily functions of higher muzzle velocities?

I, too, was thinking about the small playing fields. I am sure that snipers have miserable existence in them. A banzai charge of AEGs ends up in a massacre.

About the mods, you are right that the Japanese players seem to do a lot of fine maintenance on their guns but not too much of overt changes.
 
Would a high end/priced barrel make much difference in a stock gun? I put a wide bore miricle in my TM recoil and lost 10% FPS and didn't notice any improvement. That said, if I were to increase the air pressure it may then make a difference and thus 1J shooting makes no difference.

Furthermore, TM have been making guns for years and they have probably got the perfect combination of hop, gearbox and cylinder etc for the 290 FPS they are designed to run at.

^ You put a widebore in and lost fps.... What kind of wizardry is that? :hehe:

From what I know, a polished TM barrel is pretty darn decent. And unless you're shooting extreme distances, where hop consistency really gets important (anything around 80+ yards or possibly even less is "extreme distance" with the Japanese joule limit), you are not going to see much improvement by getting a higher quality barrel. So I think that's why the experiences differ so much between us and the Japanese. We can shoot much hotter, use much heavier ammo and thus hop consistency (which barrel quality greatly influences) is more important.

The Japanese benchmark their guns by shooting groupings at 100'. And honestly, I don't think you'll see much difference between two, let's be honest, high quality barrels at that range :shrug:

A high quality aftermarket barrel is definitely better, but a polished TM barrel is nowhere near bad. I'd take that over most aftermarket "precision" barrels, to be honest!
 
The Japanese police cracked down on the existing FPS limits after a spate of idiots engaged in drive-by shootings on the public a good few years ago. Until then the limits were ignored and nobody cared. We used to come home from our battles looking like we'd been attacked by hornets (as gaijin we were the number-one favourite targets). This was in the days before AEGs and all the good stuff was run on HPA tanks. I have fond memories of modifying a Mac-10 with a one-yen coin and some stiff wire. It could break milk-bottles at 100'. :)
 
All fields in Japan limit play at a max of .96j and tested before each game
So some players do modify , I do but my son doesnt
He and his friends like to do externals
Aeg guns have a limit of .20g bbs and VSRs have no limit except for being bio
So aegs are very limited in accuracy because of the .20g bb even with my guns max is 40m at paper targets and a friend Gungineer http://gungineer.matrix.jp/ joins 50m competions indoors and has no limit on bbs and even with his highly modded guns it is very difficult to hit paper targets
