Best cylinder/cylinder head set up to get best air seal?

[Benjii]

Hey people,

Currently, I've got an ICS M4 which has a pretty bad air seal, all the upgrades that I have dome so far are:

Mad bull tight bore
Shs 13:1 gear set
Shs full steel toothed piston
Shs air nozzle

Now I'm looking into upgrading my air seal, what's the best way of doing so and what specific products would you recommend?

Cheers,

Ben

Have you corrected AOE?

As a quick fix the O-ring on the piston head will be at fault. either replace it, or you change stretch the current O-Ring.

To do this remove the o-ring, put it over the cylinder and heat it up (using a lighter or similar)

No i haven't corrected the aoe, is it necessary? And i am just planning on getting a new cylinder set or something, which would you recommend?

Cheers Ben

I would suggest you correct the AOE if you are planning on running 13:1. What battery and motor are you running?

SHS seem as good as any for a new cylinder set. I use a SHS piston head and have found it fine.

Stick to the SHS parts.
Got the everything in SHS parts in one of my AEG gearbox (Except cut-off lever, Spring and Spring guide) which is similar to you (13:1 Gears, 14 Tooth Metal piston) with a SHS High Torque motor. Still work fine after 8 month with still 330 FPS with a SP90.

Im just running an average 9.6 wired to deans, the motor i ordered (shs high speed) does not fit in my grip so im just sticking with the ics turbo 3000, there are all different shs cylinders out there for different version gearboxes, so which one do i need? Im planning on getting the cylinder and cylinder head.

Re: Best cylinder/cylinder head set up to get best air seal?

Cylinders are usually ported to match a certain range of barrel volumes (almost relative to length, which is how they are usually listed), so thats why there are different ones. Cylinder heads are gearbox version specific, i.e. V.2 for m4's, V.3 for AK's etc...

Ah thanks for the help, so i need a v.2 cylinder head and a cylinder which functions with a 363mm barrel?

Re: Best cylinder/cylinder head set up to get best air seal?

SHS Type 2 cylinder will do the trick, SHS cylinder/deepfire 200-400mm stainless cylinder combo produces a very very good airseal (IE you wont be able to get the cylinder head into the cylinder without LOTS of oil) - ive not been able to get hold of an SHS nozzle to test in conjunction with, but I've built two setups (and my own m4 shortly as well, except im going for an SHS cylinder) with deep-fire metal nozzles, SHS Cylinderhead/deepfire Cylinder and guarder polycarb piston head (definitely worth going for a polycarb piston head if your running 13:1 gears)

The above set (with an SHS or stock piston, doesnt really matter) is kicking out over 410fps on an SHS m110 spring using a 363mm barrel.

Hey mate,

Cheers for the help! Just ordered the lot!

Cheers,

Ben.

Re: Best cylinder/cylinder head set up to get best air seal?

Shs stuffs are popular for the price, any thing is going to work ... Unless there's some big incompatibility going on.

As a guide though try to keep all parts same brand..

Re: Best cylinder/cylinder head set up to get best air seal?

Get an ICS air nozzle and get rid of the SHS one. Read the ICS M4 Bible, the guy mentions that it's best to leave the nozzle standard as aftermarket parts occasionally need modification.

Re: Best cylinder/cylinder head set up to get best air seal?

This is the major issue with ICS guns, them being alergic to almost anything thats TM compatible*


*sweeping broad brush statement alert, i know some things are compatible :P

Not sweeping, just incorrect I'd say. Out of all the parts they are made of, only a few are different. The nozzle just happens to be one of two gearbox parts that are not TM compatible.
