Colt Bolt from Brownells (223 vs 5.56)

[gan1hck]

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.

The bolt you ordered is fine

I could be wrong but I thinks Its in reference to the case diameter, colt makes good kit shouldn't be a problem.
the 5.56 and .223 difference is pressures
if in doubt call brownells

The bolt is fine. There's ONE SPEC for a Colt Bolt.

The reason I'm asking here is because Brownells' customer service rep didn't seem to know her product....ie I wasn't confident with her answer.

You guys are the experts here...more so than the customer service rep...IMHO.

.223 and 5.56 cases are identical...the difference is in the powder charges, 5.56 being hotter and in the chambers themselves, 5.56 being a little larger to allow dirt, carbon buildup, from extended firing, Firing real 5.56 ammo in a .223 chamber, can result in some serious problems, primers being blown out of the case, cases having rims torn off leaving the rest of the case in the chamber..It's not a good thing..

It would make too much sense to have some one that knows what they were talking about to answer questions
