Hey guys was hoping you could help me. I just bought my first shotgun a Mossberg 590A1 Mariner. I have only put about 150 rounds through it so far. Last time I went to the range I was having to use more force than normal to cycle the gun. I shot about 6 rounds during this difficult stage and then decided to take the gun home field strip it and take a look at it. I found some light metal gouges in the receiver. Can you guys take a look and give me your take on it please? Is this normal? Or did I not put the gun back together properly perhaps after the last cleaning. Any input would greatly help out a new shotgun owner.
