The ICS SIG AEG series are much well-received with crisp firing action and good accuracy. Now, ICS are releasing Dark Earth models of this series this year. These models 53 (551), 54 (552 Commando), 55 (551 LB), and 56 (552 LB) will be simultaneously released, but no details yet on actual release dates, but expect it to be in the latter part of this year.

If you want a 2-tone SIG AEG, then these ICS models would fit your requirements as the DE colours are basically in the handguard, pistol grip, and stock areas.
