I have a saint edge rifle and the trigger doesn't reset. I can fire ten rounds no problem then nothing I can't eject the round I have to disconnect upper from lower and find that the trigger hasn't reset. I have to use a flat head screw driver to reset trigger when disassembled only way the hammer is locked up. After that the hammer doesn't lock up for a few more rounds fired. Then back to the same. I have cleaned and lubricated everything multiple times. This happens constantly o matter if it's the first ten rounds or the after 200 rounds. Ammo manufacturer does not make a difference
