So i was lubing my bolt today and when i was done i went to put the bolt back in my Etha but it didnt want to go all the way in. So i checked if there was something inside but i found nothing. Then i checked the bolt and i found a broken bumper. I dont know if thats the name for it but it was ripped. Its not an O ring. Everytime i go to put the bolt in, it keeps getting caught on something but i don't know what it is.
This is as far as the bolt goes in.
