6.01 in an AEG

[Docv400]

...My concern is, will it fire accurately enough to prevent the BB from hitting the end of the outer barrel (the only 01 I can find is 60mm too short) although I use tape to stabilise it anyway, is this likely to result in 1/2 of my shots shattering off the flashhider, or flying in stupid directions?

BBs will not hit the outer barrel, flash-hider, silencer, or any other item that's mounted concentrically with the inner barrel, even if you swing the gun wildly while you shoot.

If the gun is moving in any direction, then everything in it (and on it) is moving in the same manner. A BB fired from a barrel moving let's say, at 1fps to the right, will have that 1fps rightwards component in it's trajectory.

You will probably get inconsistent shots though from a moving airsoft gun, because the BB will be in contact with one side of the barrel more than another, depending which way, and how fast, it's moving.

[Tecro]

Right, your explanation of the lube is more precise. Thanks.

 

However, it's not true that the BB can never hit the flashhider. The BB's trajectory is set inside the inner barrel - it doesn't change after it leaves the inner barrel. However, the barrel (including the outer barrel, flashhider, etc.) can still turn. It's not like the BB spins with the barrel if you've been waving the gun around while firing.

You might see improvement not because of the diameter, but becasue of the manufacturer. Madbull makes decent barrels, but PDI's are amazingingly good. So you may see the difference with that change, but it will be negligible, and certainly not worth the extra money. You're better off investing that money in other upgrades.

 

The 6.01mm barrels are great for snipers because the loading is bolt action. Most of the 6.01's I've seen are in rifles. They may be more likely to jam with AEG's because of full auto.

[Mofomilitia]

maybe its just arnies, but this lack of undertanding about 6.01s is outstanding.

ALL high quality bbs have an average diameter of 5.97-5.98 and never exceed 5.99. with a 6.01 the bb still has plenty of room and NEVER JAMS with high quality ammunition.

someone suggested that some of the shots might go totally off-target. i havent noticed this with mine (dees 510 mm in an ICS M16 using mostly KSC bbs) but if it does happen its very rare.

 

basically, a 6.01 WILL NOT JAM EVER if you use high-quality bbs and clean it every few months. no matter how high your ROF is.

[Thorbard]

"WILL NOT JAM EVER" seems to be a little overconfident. 0.02mm isn't exactly a big gap, and if you get dirt of some description in there, that's going to cause trouble.

DB custom barrels cost as much as buying a prometheus barrel from somewhere, but they're 6.01mm diameter.

 

They arn't likely to jam if the user had good controlled 2 round burst shots and semi auto too of course.

well I added a VFC M4QD supressor to my 14.5" barrel and added a 407mm length 6.01mm diameter DB barrel to make sure nothing touches the inside of the barrel.

Even without the suppressor I haven't experienced any fouling of the inner barrel due to the enviroment. but anyway just use clean precise AE bbs such as their .25s or TM .3's or maruzen .29s- all are my top 3 bbs of choice

[SigPro552]

I've had a DB Custom barrel for about 4 months now, and I have had no problems with it. I haven't cleaned it either, as I'm trying to determine how much filth the barrel can accumulate before ceasing to function. Unfortunately, I'm sacrificing accuracy at my own expense...

 

It should also be noted that I have used nothing but AE .25g bbs in this barrel. No cheap ###### for me.

same as the poster above i havent cleaned mine since i recieved it and htere have been no jams. it has NOTHING to do with wether it shoots on auto or semi, they are going down the barrel at the same angle anyway.

[balberoth-the-destroyer]

I'm currently looking at a DB Customs one, as I've found a place in Germany that'll export them to the UK, I'm using KSC perfects at the moment, which do seem to be very good, and the BB test on airsoftmechanics.com seemed to be very positive, so they should be ok.

[balberoth-the-destroyer]

I've just received my 363mm DB Customs 6.01mm tightbore, and I'm going to post my results with it.

 

It is installed in a CA M15A4 Carbine, with an M100, KA hopup chamber, an SRC hop rubber (temporary until I get the systema one out of my AK) using the black hop nub out of a madbull shark accelerator.

 

Firstly I'll say that the accuracy and range are fantastic, although the better BBs I tried were noticeably more accurate

I also expect it to be a little more accurate when I fit the systema bucking and tighten the hop unit adjustment wheel.

At the moment it seems to be as accurate as my VSR-10 Pro with Prom 6.03, if not maybe a little more so (up to the M15's max range of course).

 

I have fired two mags (68rd) of each of the following BBs through it, one mag on semi, one on auto using 3-5rd bursts.

 

ICS 0.25

Blaster 0.25

Blaster 0.20

Xtreme 0.20

SGM 0.29

KSC Perfect 0.25

 

Not one single jam!

 

Incidentally, the most accurate BBs were

SGM 0.29

ICS 0.25

With nothing to choose between the two that could be seen, KSC were second best, followed by the Blaster 0.25, the 0.20 performed the worse, although there was a little bit of wind.

 

All tests performed by eye from the kneeling unsupported position, some BBs curved at the end of travel, caused by the light wind, and the SRC hop rubber, I suspect.

 

In all, performance=fanf--kingtastic, I'll be recommending these barrels to anyonw who will listen!

 

A note about the retailer, I got this item from www.stormtec.com, including postage it cost 97 Euros (about £60)

It was delivered by DHL within three days.

 

I had to conduct the entire process by e-mail, everyone I spoke to at stormtec communicated in perfect english and was very polite and helpful.

I scanned my driving license and emailed it to them for age-verification (required in Germany)

Payment was conducted by international money transfer, costing me an extra £10 and requiring a trip to the bank to organise it in person (can be done over the phone, but costs £20)

 

So then, total cost £70, performance is fantastic, isn't too picky about ammo.

What's not to love?

That's great news Balberath. I'm running a Prometheus 6.03mm barrel in my m4 right now, but I'm getting a CQBR Kit so I'll need a shorter inner barrel.

Well, I figured I'd get a deescustoms 6.01mm barrel, and that's some great news for me!

[balberoth-the-destroyer]

Glad I could help, I'm still fiddling with it to find the best combination of the the various hopup parts I have, but the barrel itself seems excellent, with the more readily available selection of BB brands you have in the US, it should be far easier to find the right BB for it as well.

Thanks!

 

I've got a Systema metal one-piece hopup unit with Prometheus bucking, so I think I'll be set as far as hopup goes.

And I'm using Phoenix .28's right now, so I hope they are good enough!

Saying will not jam ever is like saying a hybrid will never run out of fuel and have to stop. Think about it, in every batch of ammo you're sure to get a Dud. Even RS Lake City (which is match grade sniper ammo, the best you can get) has duds, and those are hand made. Any BB manufacturer's QC is'nt THAT good, to make sure that every bb is 6mm. Get just a bit of dirt in it and whammo, just when you're least expecting it. Precision is good for high grade stuff, but look at the AK47, its not low tolerance, and its the most used weapon in the world...

601s are great for high accuracy and power, but you've got to make sure that you're operating 100% when you pull that trigger.

[SigPro552]

IF you clean it regularly, I don't really see there being a problem. I haven't cleaned mine in 8 months, and am yet to experience a jam using AE .25g.

[balberoth-the-destroyer]

I think the testimony of people who have been using 6.01's for months and months without cleaning then and never had a jam, outweighs other people scaremongering when they've never even used one.

[sigmaboy]

i installed a dees customs tightbore in my KWA m4 and it is amazing, i love it. the grouping are insane. i went from a 6.05 to 6.01 and there is DEFINETLY a difference.

 

EDIT: sorry for the crazy necro, i did a search and forgot to check the date, again, i am sorry for this. mods, you can delete because i cannot figure ou how to.

No worries fella.

 

As long as you're adding information to the thread it's not a problem. Respect for actually making intelligent use of the search function.

We only get the hump when you dig an old thread so you can post "LOL, yeah!" etc.

[Kye]

I too have a DBcustom 6.01, which I used for the first time last weekend. There was no jams, no double feeding, no hassle at all. I've not had time to study the groupings just yet, but there is a difference for sure.

[monkey530]

Don't you have to wait a while to get the really good accuracy due to the need for a break in?

[Raskolnikov]

Don't you have to wait a while to get the really good accuracy due to the need for a break in?

 

I just ordered a DB Custom barrel two days ago, and while on the phone with the manufacturer I was told that the break-in period for their barrels is only 2,000 rounds.

[scorch]

This is all very useful to me as I'm strongly considering upgrading...

 

Why do new barrels need breaking-in?

[monkey530]

Break in causes a "path" for the air for whatever bb's your using as long as your consistent.

 

 

Also have people been able to run biodegradable bb's through their 6.01? If so what brands?

[Stealthbomber]

Well, that's opened my eyes.

[Delfi]

Nah ...

 

'break in' is the period between ordering an item and then realising it's the wrong part for the job.
