I ordered a replacement bolt from Brownells manufactured by Colt.

After looking at the order details, I realized that it is marked as a .223 caliber on their website.

I understand that there is a difference between the 5.56 chamber and a .223 chamber, but is there a difference between the bolts????

The bolt is going into a Colt 6940, and I'm wondering if I need to return the bolt.

Sorry if this is a recently asked question, my search did not reveal any answers.
