Hello, I'm 2604:2000:8FC0:4:617F:E9A7:AF1C:4546. I noticed that you added or changed content in an article, M4_carbine, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. 2604:2000:8FC0:4:617F:E9A7:AF1C:4546 (talk) 03:31, 16 August 2019 (UTC)
