Systema Teflon Cylinder Sets

[-Dan-]

hi all

sorry if this has been asked many times, i did do a quick search but could not find any relivant information.

any ways, i have upgraded my AUG with, new piston, POM piston head with vents, metal spring guide, high tourge gears, high tourge motor, and a m120 spring.
the cylinder and cylinder head are stock as well as the air nozzel.

when i was researching springs i read that the m120 would give a fps of around 380-400,

the gun is shooting nicely but when i chronode it last week, i was getting a wide range of fps from 350 to a maximum of 378. because there was so much change between each shot im thinking there may be a leak some were? what do you think?

any way my question is, i thinking of getting a new cylinder and cylinder head, do you think this will give me a more constant fps. and if so what cylinder type should i go for?

the AUG has quite a long barrel and i was considering the
Systema Bore-Up Cylinder Set?
would this be a good choice?
the other cylinder type i was considering was the
Systema Teflon Cylinder?
would this be a better option?

i have read that bore up cylinders are better for guns with longer barrels. And teflon cylinders are better for higher rate of fire guns.

sorry for the long post
any help is much welcome
cheers

A tightbore inner barrel and quality BBs will help you tighten up consistency significantly, as will an aftermarket cylinder, cylinder head and nozzle all lubed up with quality greases.

cheers for the reply
forgot to mention that it has a tight bore barrel and i do use quality bb's.

what cylinder would you recomend and why?

You can't really go wrong with any aftermarket cylinder choice.

Just keep in mind that although Teflon has great self-lubricating properties for higher ROF, PTFE (Teflon) is a relatively soft material and scratches easily.

hay again,
does any one know the advantages and disadvantages of each cylinder?

also in the pictures i have seen of both sets it looks like the piston head and cylinder head are the silent type. can any one confirm this?

reading a breif description about the bore up cylinder its saying it has a larger diamiter than stock cylinders, im guessing this is just the inside diamiter thats bigger and the out side diamiter remains the same so it will fit into a stock TM mechbox? can any one confirm this for me aswell.
one last question, is the M120 spring powerfull enough to use a bore up cylinder?
as im not concerned about a high rate of fire, "more range" im thinking of getting the bore up.

hope you can help

N-B provides greater durability
Teflon provides greater ROF

Unless you're building an INSANELY high ROF setup, you don't really need teflon.

Correct, the piston heads are the silent type, although the bore up head sets are larger outer diameter.

Correct, the inner diameter of boreup cylinders are larger, the cylinder walls are thinner, so it will still fit standard gearboxes.

And yes, the M120 is powerful enough to push a bore-up cylinder. In fact, it is the absolute minimum spring required in order to power the bore up cylinder as spec'ed by Systema.

Keep in mind that the weakest bore-up setup will push you well over 400fps, which as far as I know is illegal in the UK to break even 1J.

cheers for all your help illusion,
500fps sniper rifles are allowed at the site i use, and i have stopped the aug from being fully automatic, im hopeing to turn it into a light weight sniper.

thanks again.

yet another question!

i have the chance to get a bore up cylinder set for an M4, for dirt cheap.
i know the M4 uses a version 2 mechbox and the aug has a version 3 mechbox, but is there any difference between the two when is comes to the cylinder and cylinder head?

will the bore up set for an M4 fit the AUG?
although i can get it for cheap i dont want to waste my money.

No, they will not work. V2 and V3 cylinder heads are not compatible, and even different cylinder heads between different V3 guns are not compatible. You need, specifically, an AUG bore-up kit.

crap!
ok cheers for your help.

And on top of that, the M4 bore-up cylinder is ported. It's usable volume would be too short for your intended purpose.
