ICS M4 Upgrades?

[M.Garcia]

I have an ICS M4 and I'm looking to put some parts into it that will make it more reliable and up to par with some higher end AEGs.

I'm looking for some input from the community on what they think I should put into it. I'm not looking to revamp the ENTIRE thing, just looking to make it more sturdy and more reliable (no issues after 8 months of use).

So far all I have put into it is a Madbull Tightbore.

I appreciate the help!

does it have a metal receiver?

[M.Garcia]

Yes it is all metal.

change the piston and piston head, same with the cylinder head, if you have stock parts in it.

Going to go in the order of importance to me at least.. and will exclude the tightbore since you've already got that covered.

New Piston. I've had mine gamed 3 times and a piece of the stock piston blew the fuck off.. Lucky I had a spare one kicking around at home, and I had a secondary gun to use.

Hopup rubber - cheap upgrade so definitely worth it

New Cylinder head - better airseal is pretty important to have.

A solid sping and spring guide - usually bought together and you defintely don't want to keep the plastic one they provide.

Metal body (if you don't have one already) - very hard to find, and also with the older metal bodies sometimes you'll find that mags might not seat properly... just use electrical tape on your mags or in your mag well to have it seat right. (only SOME mags have this issue)

I think that would probably be it for me... especially since you don't plan to revamp the entire thing. I think the most costly thing from that list would be the metal body... if you dont' have one already.


for the extra stuff you might want, but I don't see a real benefit for me.

Motor - something with a higher rate of fire, but I rarely use full auto spray.. maybe burst, but with the slower ROF means I can keep peoples heads down longer

metal shims and buckings for your gear box - not too pricey, but I wouldn't do it unless something breaks

LiPo battery - it will put a bit more strain on your internals, but shouldn't be much of an issue. Also might want to know when your battery is running low on juice. Don't want to fry something accidentally.

Spring for charge handle - I've noticed this spring to be a little weak and sounds terrible so I swapped mine out

Any other external cosmetic stuff... RIS.. front sights.. rear sights.. scope/red dot.. vert grip.. cheek pad rest... magpul MIAD grip (this is the customizable one so you can get the perfect grip on your gun)

I do have a metal body already. It is a 2010 model.

what model is that? all I know is olympic arms and M&P are only made in North America and COLT version receivers are made in Asia

[M.Garcia]

M&P

while we are on the ICS topic, are ICS split gearbox lower receivers different from the normal ones?

[M.Garcia]

Split gearbox lower receivers? A gearbox and receiver are two different things. And yes the ICS gearboxes are different than other AEG gearboxes for the simple fact that ICS is a split gearbox, and most other makes are not.

yes very different.

[ACCL]

ah ok.

[Blacksheep]

most of the upgrade parts are the same

[sundae_1021]

Someone here with a plastic handguard had tried to install a RIS handguard? Cause I bought a RIS and put in on my ICS M4, and it wouldn't lock tight. I can pull the lower part easily. And I am planning to buy a sling adapter, but I want to make sure I won't waste another $$..
