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
