Barrel and BCG question

[BIGWHISE]

I am shopping around for barrels, and found a DPMS that I like. I have an Armalite upper.

My question is will an Armalite BCG work with DPMS barrel, or use a DPMS BCG, or use an Armalite bolt carrier and DPMS bolt.

Thanks for any help

Either carrier is fine as long as you use a DPMS bolt.

The bolt needs to match the barrel extension

That is what I was guessing, just wanted to be sure.

Thanks
