5.56/.223 Upper from KMTactical

[19_A_CPT]

Have an upper and BCG/CH on the way from KM Tactical in Missouri. Seems to be a standard upper and such, however, I am curious as to whether or not it is a 5.56 or a .223 barrel because as its described it looks as it may be either/or. It does have a note that it would be a Wylde chambering depending on stock availability of those barrels. I guess i could be that guy that asks the warehouse but hate to bother them. It did ship out today so im excited to get it in and start shooting. 

What would your best guesses be on if its a .223 or 5.56 based on the listing?

im not one to dive too deep into the 5.56/223 differences, but curiosity has already killed one cat. 

This will be going on one of the Dont Tread on Snek Lowers that i recently bought on TGO.

When you have it in hand, it should be stamped on the barrel.

Generally anything marketed as 5.56/.223 is a 5.56 chamber.   But your best bet is to check the barrel markings when it arrives.  And even better than that, is to throw a set of headspace gauges in it.

.223 Wylde is a hybrid chamber capable of consuming .223 Rem or 5.56 ammo without any major issues.  Sounds to me like this is their way for saying this is what we plan to use but be prepared to receive whatever you get.

It ended up being a 5.56 upper. Not disappointed at all. Seems to be very well made
