...if you took the bolt apart , you now know why everyone buys a bolt tool. On the hammer spring , you do know it goes in from the side of the hammer WITHOUT the notch in it , right ? And the trigger spring tool makes that a snap. And it's easier to assemble the trigger / sear / spring outside the trigger housing , held together with a pin as wide as the trigger , then aligned in the housing , using the real pin to push the short one out.
