2. On the right-hand side of the gun, in front of the trigger, is the handle lock, which is a pin with a small projecting lever resting in a horizontal position. Turn this lever upward and backward as far as possible. Withdraw the handle lock. This releases the handle, which then can be removed rearward. The handle contains the mainspring, hammer, sear, sear spring, trigger and trigger spring. To remove the hammer and mainspring from the handle, pull back the trigger, release the sear by pulling the nose down, when the hammer and mainspring will fly out, as the sear holds them in place.
3. To remove the bolt, throw the gas lever rearward as far as possible, and while holding it in that position insert the small end of the handle lock in the hole on the right hand side of gun, pushing the handle lock in as far as it will go. This removes the bolt pin from the bolt. Withdraw the handle lock pin, but leave the bolt pin in the position in which it now is—i.e., projecting from the left side. The bolt is now free to be removed from the rear of the gun.
4. The extractor and firing pin can be removed from the bolt by pushing out the small pins that hold them in place.
