Colt published a safety recall today. The recall has occurred because Colt identified that some hammers that were out of Colt specification were used in some rifle/carbine assembly since roughly March of 2021.

Colt has set up a good website that has a lot of information to include firearm model, lower receiver markings and serial number ranges affected by the safety recall. The website is a one stop shop for information and serial number submission to Colt. The website is https://coltrepairmsr.com

I have done a short video about it on my Instagram page at this link Video About The Colt Safety Recall

Here is the screen that you will see if you enter a potentially affected serial number. This screen was displayed when I entered the serial number for my CR6920-EPR.
