Ok, I just finished building my first lower in preparation for my PSA Upper. Took my time and all went well but my question is can you not put the safety on when the hammer is down? If I have it cocked I can place it in Safe and you can not pull the trigger, move it to fire and pull the trigger, holding the hammer so it does not not slam the receiver and it will fire. But after firing I can not put it on safe.
