The prommy 6.03 and PDI 6.05 are high standard, super polished, stupid accurate, honed out stainless barrels, and they've been the basis of comparison for every other barrel.
The PTW barrel even at 6.04 is more concentric than any other brass barrel on the market

The 6.08's are primarily AEG OEM barrels made on the cheap, so it's quite rare to run into a fairly concentric and accurate barrel outside of marui

But with higher quality wide bores, like the orga 6.10 and 6.13, we've found them to have the same accuracy as the tighter bore barrels, and maintain their accuracy longer.
Problem is we still don't have anything in the 6.06-6.12 range for AEG's that comes close to the PDI 6.05/prometheus 6.03 quality

As well in the PTW world, right now the two best reviewed barrels are the OEM evo 6.04 and ORGA 6.10, reviews saying they're on par with each other


Switching to the 6.20 barrel, I'd recommend actually changing the cylinder as it's a pretty significant change in volume. As well expect to lose 45+fps
Going from a 6.04 to 6.10 PTW users generally lose 25-30fps

PDI makes a 6.08 CHF barrel.

With most bbs measuring 5.95 these days, I think 6.03-6.05 is the sweet spot. Just my opinion. Someone needs to make an accurate set glass barrels at various diameters and use high speed photography to show what the bb does.

Not to hijack the thread, but how do you prefer to clean the inner barrel when fouling does occur?

There is no way I'm paying $80 for a brass barrel.

That having been said - (I'm not even sure if this matters since brass is so soft) - how's the bore quality?

I have not used it yet, but I have been using brass stock 6.08 barrels in most of my builds for quite some time, so this is still bigger bore (yet slightly smaller) and should in theory be more consistent.

I find the brass much better than any aluminum or fibre glass composite barrels/hybrids and any tightbore I have used. Those never gave me the results I wanted. I find the brass does not vibrate as much as these types of barrels, maybe because it is softer and heavier? Is the brass more forgiving than a steel barrel, could be, I do not really know but I know what has worked for me so I stuck with it. Brass barrels are easy to clean and polish as well with a C7 cleaning kit brass jag and 2x4 patch.


I always went back to stock except in one gun I have that has an unknown barrel (It is grey and at least 12 years old and it does work really well how ever it was designed but I have no idea of the make or model (could be systema or maybe guarder brass barrel coated in a silver-grey colored Lucid Chromium Plating metal ?)

With windex
eats through grime and grease and evaporates without leaving a film

Silicone essentially coats the barrel in oil which attracts more dirt

And there's nothing wrong with brass barrels. They get chewed up under heavy fire in M249s and such, but accuracy wise they're great for DMR's
PTW's have been using brass barrels for a long long time, and right now their EVO 6.04 is just as good as the leading aftermarket barrel

Would work great in my P*, but I already have an ORGA 6.23.

Any updates in regards to the improvements that the Delta Strike or the Magic Box IBs made?
looking to order either of these items for my newest build. which is going to be flat hopped.
That being said, i figure that i will need a bore up kit for the delta strike. but standard cylinder should be fine with the magix box IB?
please correct me if i am wrong in assuming this.
