I have a complete DPMS upper with a 24" bull barrel. It came with a complete BCG and the upper was labeled 223 and to not shoot 5.56. I'm in the process of building a complete lower. I'm going to get a DPMS stripped lower and put a two stage trigger in, and an A2 butt stock. While I have the wallet open I was thinking of adding a complete Nickel-Boron BCG. Will upgrading the BCG allow me to shoot 5.56 rounds or must I also change the entire gas system?

You would need to rechamber the barrel to 5.56 or get a barrel that would allow you to shoot 5.56 .There is a chamber reamer made that allows both to be used it's called a Wylde chamber.Just changing the BCG will not change the chamber to 5.56.

I guess that makes sense. Thanks. Maybe I'll have that done when I have the barrel fluted.

The BCG has no real bearing, it is the barrel/chamber as pcj says.

As long as you seat your bullet, correctly in relation to lands and work load up accordingly, no need to change throating. About the only time it's an issue is with surplus 556 ammo loaded with 62gr steel core green tip and bullets with similar profile.

So if we buy a new riffle chambered in 223.when we hand load and move the bullet closer to lands.arent we increasing pressures to about the same as shooting a factory 556?I think Robertmt is on the money when talking about seating depth.i have been just pulling out any 556 brass and loading only the 223 just because of this unknown.

556 cases are all over the place on weight and internal volume.
For the many that I have measured.
There are also many .223 cases that will match the weight and internal volume of the 556 cases.

I have loaded my accuracy load in in different cases including 556 cases. Never had any issues.
Some 556 cases were compressed loads some were not that is also true for the .223 cases with the same load.

I am all about the accuracy though and found that the federal cases give me my best groups.
I do not even sort the federal cases by weight.

Yea I get a flier in the group but the groups including the flier stay sub MOA all the way to 500 yards the farthest I have shot for a group.

I also anneal every time. more even bullet seating pressures.
I use a VLD chamfer also.
Now all my .223's get federal cases. I feel like I am wasting bullets sticking them in other cases.
