Hey gents.
I hate M4's but I jumped on this one last year as it was going cheap brand new at a local shop. (ICS CXP-15 Proline metal). It was a pistol style only M4 with no stock. I bought it to be upgraded straight away.
Prommy Tightbore barrel
Maple leaf flat hop.
ICS Metal Hop unit.
Short stroked piston.
New spring.
New ICS pistol grip (Old one broke during the upgrade process, the new style grip needed a lot of fettling and swearing from my tech to go on)
Mosfet.
ICS QRS Stock
SRU foregrip
Holo sight.
Canted Ironsights (Because they look kickass.)
Managed to blow the fuse first game as it was the one for 7.4 lipos, need to get the 30A. Also the ICS high caps weren't feeding fast enough in full auto so had to use my Nuprol midcaps.
I also have the Mag short midcaps, which looks better do you think? If I am to use the Mag short midcaps i'll need to get a stronger spring for them to feed well.
For an M4 it looks alright... I guess...
