The magazine that came with my FX wildcat was not set up properly ( pellet doesn’t advance it smoothly due to low spring power). So, I jammed the barrel with few pellets and I was stupid enough to use one steel rod trying to clear it without even removing the moderator and barrel. Without knowing where the exact location of the jam I applied a mild pressure by hammering it but the pellets never came out . After spending a good three days to put the magazine back without success, I realized that the barrel has taken all the pressure and pushed out a piece of metal in the chamber ( picture attached). I filed the protruding metal off but looks so ugly now, lesson learned
