Few question for the advanced players

Eminence

First of all when upgrading a gearbox would you recommend systema or ultimate? Which are higher quality?

When it comes to gears looking at speed which ratio is faster eg. 14:1 or 17:1?

Would you reccomend a tightbore or a tanio koba twisted barrel?

If heard that excessive tightness is not recommended that 6.01 will be worse that a 6.03 is this true ?

Honestly neither of them Systema is crazy money and ultimate is meh.

What do you want out of your AEG?

I personally use 6.03 Madbull Black Pythons in all my guns - because they work, I've seen an awful lot of mixed results with twist barrels and they're aren't suited for quick double taps or FA.
6.01 is too much to be honest unless you use extremely high quality BBs and are very careful, cos they can jam up easy. 6.03 is ideal.

Im converting an m4 into something going by a sniper rifle which can be easily changed for cqb, so two motors, two barrels,
1. Looking for distance for the sniper
2.Looking for rof for cqb

p.s didnt answer the question about gears, if you could please.

Right, firstly - you limit your barrel length to the cylinder you have installed in the gearbox. So for CQB - I presume you'd want a short barrel (310mm or so), this means you need a cylinder for a barrel that length, which would be a type b cylinder, the longest barrel you can use with that is roughly 400mm, so that'd be the longest you could use.

The barrel only does so much for accuracy, there's even debates that a smooth, polished stock barrel is more accurate than a tight bore - but we won't go into that.

Range and accuracy are mostly down to the hop up rubber - I've a rifle with a 455mm tbb and Modify hop rubber - it hits roughly 60m and I can hit a man sized target at 45-50m with it. But I've an M4 with a 280mm barrel and I get the same range and accuracy with it, I use the same hop rubber.

For snappy trigger response I use VFC gears, an X-hightech piston, a Guarder Durable, Deans connectors and a 7.4V 30-50C lipo. So I get an almost instant semi and a mean ROF (28rps), but the motor burns out in no time - it eats power and the insides expand and seize up. It's completely impractical. so the best option is a G&P M120 motor - with the same lipo I get a great trigger response and a slightly slower ROF. But I'm more a semi player anyway.

For the sniper - a 400mm TBB and Guarder clear rubber will get you excellent range and accuracy. For CQB a 310mm barrel and Guarder clear will be the same

Hope this helps.

Gears - 14:1 is faster than 17:1. 14 rotations of the motor will give one one rotation of the gearbox or something like that, can't remember or I'm too tired to thoroughly think it through.

no need to swap motor... high rate of fire will just equal fast trigger response in semi for the 'sniper' version.

One idea is to keep a second upper reciver, with long barrel, or long front end, with scope on, and hop and barrel in. Just swap and go.

Eminence

the advantage is i got an ics, the gearbox splits in two, so i can have two gearboxes and two whole complete outer barrels as they are extremely easy to change.
Since i can use one motor that will help.

You said that Ultimate is meh, do you mean just the motor or the whole series of ultimate parts?

Leftyflip

I just don't like their parts, some of them feel cheap and are over priced - especially when you can get better parts for less.

Just on the note about tightbore barrels - I used to think that 6.01 mm tightbore's were too tight, and 6.03 was the way to go...then I used a 6.01 and got far superior results in range, power, consistency in power (a variance in joules of 0.001). I was hassled into trying out a JBU tightbore, which come in 6.01, so I decided to test it against a couple of barrels.

I tried Madbull Black Python II, which I'd been using until then with great effect (in other guns), a Deep Fire 6.02 mm, Vanaras 6.03 and the JBU 6.01.
- Stock Barrel: 0.86 J, variance of 0.02 J
- Madbull Black Python II: 0.88 J, variance of 0.01
- Vanaras: 0.87 J, variance of 0.02
- Deepfire: 0.89 J, variance of 0.02
- JBU: 0.91 J, variance of 0:001 J

In terms of range, Vanaras and Madbull improved stock, but were equal to each other in terms of raw range, and consistency. That said, the stock barrel is 80mm shorter, so grain of salt. Deepfire imprived marginally on the Madbull and Vanaras barrels, but it is so marginal that taking an increased risk of jamming outweighs the gains. JBU showed significant improvement in range, power and most importantly consistency. I use King Arms/old G&G BBs exclusively, and have thus far had ZERO jams. That said, it means I can't trust a team-mate's mag in my gun...however I do believe that the gains in this instance do outweigh the risk. Why? Superior range, far improved consistency in shot-to-shot groupings, and in power (much lessened variance).

That said there are a lot of barrels out there, and I've not tried 'em all. It's entirely possible to get better results from a 6.03, so the above is in no means infallible, just my observations when vuriosity and bordem got the better of me.

PS: All barrels tested, bar the stock one, were 363mm, and were used with a G&G Green hop up rubber. The gun used is a CYMA M4 CQB, gearbox and hop mech are completely stock.

Thats helpful if you dont mind me asking where did you get your 6.01 from ?
