Slender Airsoft reviews the Echo1 Special Operations Branch 2 (SOB2) AEG they got from Echo1 USA to review. This is the MP5 series from Echo1 modified to place more rails on top and at the handguard area to be able to mount more weapons accessories. The SOB2 is the version that has the 4 position folding stock and battery is installed at the front area.
