Magpul MOE SL handguards, MOE K-2 grip and STR buttstock all in FDE color on my Expanse M4 carbine.
I only have two out of three, the handguards and the grip, I don't have the buttstock yet but tried it at my local gun shop and it fits snug so it's on my next to buy list.
The handguards was a bit difficult to install, I tried it 3 times and finally it went in on my fourth try, my handguard installation tool slipped the first three times I tried to install it.
After I installed the handguards it is very snug fit, no movement at all on my Colt Expanse M4 upper, it have a longer length than the standard carbine handguards so I could place my support hand more forward about under the FSB.
I also have the SL grip but it will be going to my other 9mm carbine, it is smaller for my large size hands but the 9mm I will put it on are mostly used by my wife and kids.
