This is ridiculous. I’m shooting my Impact tonight when suddenly things felt strange chambering a slug. Pulled my mag to see how many slugs I had left and noticed an oring inside my mag. Thought no big deal it’s probably my probe oring. It’s not. Probe oring is fine. I measure it and it’s 5.5x1.5mm. Look at the parts diagram for my gun and the only 5.5x1.5 is in the valve tube end. You can see the oring is worn but since I haven’t taken the gun apart yet I’m curious if anyone else has had this issue. In the second pic the oring in question is 25.1.
