You cannot successfully utilize a bore-up kit without the use of a bound that as at the very bare minimum, equal in strength to a Systema M120S (~420fps) or college. Otherwise, you will really lose additional power.

I've mentioned this theory lately, that:

Tighter bores = higher FPS, simply reduced grouping tightness
vs
Wider bores = lower FPS, but tighter groupings.

Granted, this theory did not come up out of nowhere. There are multiple very big barrel manufacturers which attest to this - the first of which, was Systema around 15 years ago, who was also the Kickoff mass produced aftermarket manufacturer on the market. Their 6.04mm barrel still remains every bit one of the highest selling "tightbore" barrels available. (There are other factors at play in regards to this, based on market demographic, business aspects and such, which I'll leave out of this word.) Playing with many diameter says, they came to the decision, that six.04mm was the "perfect" compromise of power and accuracy.

KM/Head1950 quickly followed suit with their release of a TN coated brass butt, also using a half dozen.04mm diameter. The inclusion of the TN coating yielded a longer lasting terminate, likewise as self-lubricating properties to reduce friction, reduced oxidation, and ease of cleaning.

PDI presently followed accommodate with the release of three barrels to attain the needs of a larger audience. Some users wanted tighter bores for higher power, whereas others were willing to sacrifice some power for tighter groupings by sticking with a stock bore. Using college finish manufacturing techniques for greater concentric tolerance and higher quality materials (Japanese grade stainless steel), PDI created the first line of inner barrels which proved these theories. They striking the market with all iii bores at the same time: 6.08mm, 6.05mm, and vi.01mm. In their opinion, and peradventure to set themselves apart from the competition, half dozen.05mm was determined to exist the "perfect" bore compromise of both power and accurateness. They openly advertised that the half dozen.08mm bore had the greatest "acquit" and to the lowest degree power of the 3 bores, whereas the 6.01mm had the least "bear" merely highest power output of the three. The half-dozen.05mm was placed squarely in the middle. This was the beginning great proof to the theory, as they finer eliminated ALL OTHER VARIABLES, including manufacturing tolerance, blanket(southward) (or lack thereof), manufacturing techniques, length, crowning methods, window dimensions, etc. The ONLY difference between these three barrels, were the inner diameter, and by extension, the wall thickness.

I saw PDI's marketing materials on this as early on as 2004. It may have been around even before that. Systema and KM were out earlier I came in to the scene in 2001, so I don't know the timeline on those products.

Laylax came back with their own argument that refuted PDI'southward claim that vi.05 was the perfect bore. Later all, who is PDI to say what the best compromise was? For the Japanese marketplace, most of their engagements were very brusque to medium length engagements, and thus, Laylax ended that their customer base was willing to sacrifice a bit more than accuracy, for power efficiency. Thus, Laylax produced half-dozen.03 bore barrels under the names Prometheus for their AEG line, and Ix Ball for their pistol/SMG lines.

In my opinion, from 6.03mm to half-dozen.04mm, and from 6.04mm to 6.05mm, the differences in power and accuracy are so minimal, that it would be negligible. This forms my opinion that these companies are doing this simply to prepare themselves apart from their direct competition.

It'southward my ain personal conventionalities that LayLax barrels (Prometheus, in particular) accept become the most pop, simply because their offered manufacturing tolerances very close to PDI, a quality very shut to PDI, at a significantly reduced toll. PDI barrels, as dainty equally they are, comport a massive premium that many consumers simply cannot justify. As such, Prometheus has at present grown to be one of the nigh popular tuner barrels.

Laylax hasn't ended there. But recently, (in the past year) they've released Nine Brawl 6.00 "POWER" Barrels, which do exactly as it claims. It produces more power, with the advertised caveat: wider groupings. All the same, another manufacturer removing all other variables and proving the theory.

This projection has been in the works past Laylax for at least 2 years, as the theory was already causing farthermost tuners in Asia to play with very farthermost ends of the spectrum. Laylax merely decided to have it to mass production.

Orga, at around the aforementioned every bit Laylax's release of their "Ability" barrels, came out with their 6.13 and 6.23mm wide and ultra widebore barrels to take the farthermost to the other end of the spectrum.

"The proof is in the pudding", every bit they say, as on paper, all of these claims are verifiable.

While I did not disbelieve these claims, I had to meet it for my own eyes. Thus, I commissioned a custom barrel manufacturer to turn out a full range of brusque barrels to test this theory for myself. I went even further with the spectrum, and got barrels as tight as 5.98mm, all the mode up to 6.23mm in increments of 0.01mm. A few less pop bores were left out of the order to save me cost (ie, 6.06, half dozen.07, 6.09, six.11, 6.12, and everything from 6.14 to half-dozen.22mm), and I've simply washed a very rough examination between the two extremes of the spectrum and then far. v.98mm versus 6.23mm. The difference was noticeable.

On the initial test of the v.98mm bore, the accuracy was crap. It was theorized that the extreme tight bore exaggerated whatsoever irregularities in the projectile and also in how straight the barrel was crowned. Whatsoever irregularities at such an extreme diameter acquired a lot of turbulence at the muzzle as the projectile was sharply introduced in to the atmosphere. Thus, a solution was created to soften this introduction of the projectile into the atmosphere, and it drastically improved the tightness of groupings. I cannot divulge much near this technology every bit it's all the same in the works, only let's just say it'southward functional, and combined with a few other technologies, ILLusion Kinetics is working on some extremely high end ultra tight diameter barrels that will have groupings nearing the widest broad bores while retaining huge ability gains.

With Howdy-Capa v.1 length (112.5mm) barrels, I tested these two bores, and noticed a 0.4Joule difference betwixt the two. At a 100 foot indoor range, I was able to get a group of 11" with the 6.23mm diameter, versus a 13" group with the five.98mm bore, using Tokyo Marui Perfect Hit 0.28g BB'south. This ii" grouping is dramatic, but purposely and so, and was why I chose a short butt platform to test this, as it would most likely exaggerate this theory. Also keep in mind, this upshot is with the newly revised 5.98mm bore, versus an otherwise normal 6.23mm bore barrel with your typical crater cut. The additional applied science that these barrels have over standard barrels, is that these are bull barrels. The outer diameter of the walls are slightly larger than your typical barrel, with the purpose of reducing vibration introduced inaccuracies.

The proof is positive.

The adjacent step is to minimize more variables in the tests, also equally to examination all of the other bores to find out what

MY

perfect compromise would be in terms of grouping and power output. For what it'due south worth, with pistol use, I would rather get with the tightest bore for the drastically improved power efficiency, every bit the grouping difference for typical pistol engagements doesn't warrant the ability loss to me. Information technology might brand a difference to y'all.

The next step in the theory, is to test with longer bores - particularly, with AEG's. Unfortunately, the cost of this is much higher, so whether I get to that stage or not is nonetheless up in the air.

Besides, I've been told that a standard cylinders tin can simply handle up to 500mm.

In my experience, standard diameter cylinders are good up to 550m. Above that, you will need a widebore cylinder setup.
