I want to upgrade my ICS M4A1.

Here is a list of what i want to buy.

-Socom gear daniel defense mk18 9.5 inch rail
-G&P M4A1 Extended Battery CRANE Buttstock w/9.6v Battery
-Magpull moe hand grip
-Pmag 75rnd mags
-Madbull 6.03 363mm black python thight bore
-DNTC 308 Black ccw 14mm flashider
-modify piston full teeth v2
-modify piston head v2
-modify rotating spring guide for v2
-Modify S100 AEG Upgrade Spring (369 fps???)
-Magpul PTS ASAP M4/M16 sling swivel

Anyone know if some of theses parts wont fit/or need modification on the ICS?

Been a while since i upgraded a m4a1... did own an ICS m4 a few year back but never upgraded it (except for metal bushings)

Help would be very welcome
Thanks.

PS... Just saw i posted in the wrong forum... can a mod move it to upgrades and modifications? thanks

The Magpull grip may need some filing but nothing major. What brand PMAGS? Madbull tight bore inner barrel will be good, going to be getting that as well. I'd also suggest upgrading the hop-up. That flash hider looks good was thinking about it, no experience with it though. Should have no problems though.

For gearbox mods I don't know much about, but the S100 will get you maybe 350 FPS or 360. Better off to go with a 110.

Even with the tightbore and new piston head? They are listed at 369fps wich is enought for me. s110 are at 410fps.

The pmag are the only one airsoftparts have so i think they are Madbull green label...
anyway; will try them and see for myself...

I already ordered the parts.

Well I'm not quite sure. Find my topic about ICS M4 upgrades. People posted about it.

If you want, come see me when you received your parts. I have built a few ICS based rifles and most part will fit with very little modifications.

You want to get the newer white Modify piston with the first tooth removed (I think they call it high speed).

A S100 will get you to about 340 fps if you have a VERY good airseal, but most probably around 320... rule of thumb is (M/S x 3.3)-20 = FPS will be a decent estimate...

Keep the stock hop-up chamber, but upgrade the rubber to a Guarder clear or Prometheus purple. It is possible to install an aftermarket metal chamber with some minor modifications, but the stock ICS chamber is way more efficient.

PM me if you want to drop-by... I am in Longueuil... if you are still in Brossard for now.

You should end with something similar to this, minus the G5:

After M.Garcia comment last night i asked Jugglez to put a s110 spring in my order + the s100... Guess I'll install it first and keep the other one for CQB. BTW; Do you know a place that sell upper shells for the ICS M4?

I bought the purple Modify piston...Hope nothing wrong with this one?
The other as you say was for high speed gear. For the hopup chamber i knew it was proprietary to the ICS. Prom soft rubber were out of stock sadly but will order some next time (ICS one will have to do for now.)

Thanks for the offer but i'm quite able to do all the mods myself (did it on most my brother and my personal aeg's) and that's what i like about airsoft... playing with the gearbox and other components. Never been to a gun doc since i started the hobby.

Anyway should have my parts soon, thank to Jugglez incredible mail service!

I ordered one... didn't know that there was problems putting them on a ICS...

In my experiences, the stock cylinder and piston heads sealed great, just putting a modify nozzle on increased compression to perfect. I recommend the ARS hopup rubber, and a tightbore (I installed a Systema). A bearing spring guide is also a good plan. Can't comment on the rest of the externals.
Also the PMags should fit and feed well, but be aware plastic MAG mags do not.
Also I love the hop-up unit. I've worked on many styles of guns and next to the TM M14 it is my favorite.
The above comments were meant for the cansoft version.

I have the full metal ICS.

I used mag brand plastic mags on my old ICS M4 and never had any problems with them.
I plan to buy the hopup rubber in my next order (with a couple others parts i forgot to buy).

The only thing that worry me a little is the installation of the magpull grip... KosMos???

[Kos-Mos]

The magpull grip is the easy part.

You have to grind 1mm on the front section where it meets the receiver. When you try to install it without any mod, there is a 1-2mm gap at the top and it does not sit properly.

When you do this, you might also have to enlarge the motor hole a little bit to let the motor slide in the mechbox perfectly.

The hard parts will be fitting the stock and DD RIS on it. If you are lucky, your ICS rifle will have metric treads. If not, you have to rethread the upper receiver for metric. Either with a dremel and a lot of time, or with a die.

You also have to modify the buffer tube holder prong. The small tabs on both sides are made taper in both axis. So you have to file the rear part in width and each tab in thickness both sides. If you don't, you won't be able to use the buffer tube that comes with your stock, and the ICS tube is known to be a tad bit larger than most others.

You can order upper receivers and spare parts from blazingtoys.com and speedytoys.com. Both have a decent inventory.

Thanks

For the installation of the Daniel defense;
Does the ICS have the same upper receiver threads as the g&p has?

[Able1]

please post a picture or a diagram i really wanna get it right the first time!

[Kos-Mos]

Sometimes.

If you have an old Olympic Arms one, yes.

If you have the newer Panther Arms one you have 50-50% chance.

I don't know yet for the Colt one...

The one in the picture was an Olympic Arms from 98...back in the days. I had to work the treads to fit the Madbull Noveske 10" rail on it. There was no "Standard thread adapter" when I did it.

As for the MIAD/MOE grip, you will have to try.

Basically, when you fit it, the surface that hits the receiver first has to be grinded down until the grip fits perfectly. Then you have to look into the grip to see how much you must enlarge the hole, usually towards the back (since you just grinded the front of the grip).

Takes about 1h with a dremel, but do the final touch with a fine metal file. Gives a strait edge and smooth finish.
