I bought a Or3Gun Enhanced Competition Follower and installed it in place of the factory one in my Mossberg 930 SPX. I was unable to load the 7th round after I did this. I removed this little white plastic part from the magazine tube and then it worked fine.
What is this part? There is no mention of it on the Mossberg Website and it does not show up on the parts diagram. Is it critical?
