The
front Set:
Pull the push pinn from the front part of the body (t is right beside the back sights) push the front set forward and unscrew the barel. if you want to take apart the whole front set , just find the smallest alen wrench you can find and start uskrewing all the small alen bolts.
The Body
Its pretty easy , take out 2 push pins in the back of the marker( where the body and the stock conect), after take look in the spot where the stock was and you will see silver chunk of metal with the alen fitting in the middle (the alen fiting is the velocity ajuster) You have to press with your finger on that chunk of metal and twist it( Doesnt matter with way) untill you will feal the thing pressing harder against your finger, give it some slack and it will pop out. You will see the round chunk of aluminum, the spring guide and the spring in your hand. After luling them out cock the marker and the bolt will slide easily to the back. pull out the cocking handle and use it to push the bolt even further back, eventualy it, the buffer and the striker will fall out of the back.
