ARs can get pretty messy sometimes. Unless you're running into reliability problems, you don't have to stress over making everything look super shiny. But if having a clean chamber gives you some peace of mind (and I totally get that), using a chamber brush and a good carbon cleaner can make a huge difference.How do you guys clean the star chamber and locking lugs on your AR-15? I feel like my routine with the brush, bore snake, and Q-tips just isn’t working. What's the trick?
