In airsoft, the majority of guns are meant for a right-handed operators to use, and lefties just have to be OK with it. The ECHO1 ASR is one that can be used ambidextrously. It takes about 10 minutes to change over for a left-handed user.
In order to make you ECHO1 ASR Left handed, it may be easier to start by removing the stock. This can be done by pulling the lever on the stock down, as opposed to up, and sliding it off the back. You can then start by cocking the gun and leaving the bolt to the rear.
You are now ready to begin disassembling the bolt. Start by using the larger hex key, and unscrew the hex screw on the very back of the bolt, removing the cap piece at the very back. Make sure to keep the hex screw with the washer and bolt cap.
Next, remove the spring and grey pin inside the right side of the winged piece that holds the bolt handle in place. Then remove the winged piece, and be careful not to lose the gold pin in the spring on the underside of the wing.
Next remove the bolt handle, and using the smaller hex key unscrew the hex screw holding the black handle to the right handed piece. Then fit the black handle to the left handed piece, and slide it back onto the bolt.
Reposition the gold pin/spring and the grey pin/spring to the left handed side of the winged piece and slide it back onto the bolt.
Put the bolt cap back on to the end of the bolt and tighten the hex screw back down. You can now slide your bolt forward and you are ready to use your ASR left handed.
