Barrel come loose

[robertalcorn]

Hello,
I’m having some issues with a used Remington 870 mag tube cap. The cap will often unthread itself slightly, making the barrel come loose under normal usage. Any ideas on why this occurs or how to fix it? Thanks

I think suggested solutions may include checking for damaged threads, using thread locking compound, or ensuring proper tightening technique to prevent the cap from loosening. Addressing this issue is critical to maintaining the performance and safety of your pistol.
