I want to replace a sub gun trigger with a cassette style trigger to test function. The gun is my SMG 45 and supposedly any AR style trigger will work but I had unexpected and unsafe results with a Geissele so I think a cassette style might do better. I know zero about them so I am looking for some insight and one that has a good warranty should it break apart. The factory trigger has a bar that rides over the disconnector and it would not install on the Geissele.
