One of the most important things is to take the bolt out and clean it out . I take the bolt out of the reciever and out in the back yard and wearing rubber gloves blast brake rotor cleaner through the bolt . make sure the wind is'nt blowing your way. when you hold the bolt in your hand and shake it back and forth your going to want to hear the fireing pin slam back and forth freely.
you want it to free float. don't oil the fireing pin . don't put any oil on the gas piston either. a very light coating of quality oil inside the reciever and on the outside of the bolt is perfect. and if you fire corrosive ammo - military stuff take it apart and flush the barrel with boiling water then run a patch through then a nice light oiled patch .
they are fun to shoot and very reliable. have a good time .
