New BCM 14.5" barrel. Certain round count before using .22 CMMG conversion?

I know the consensus is there is no need to break in a chrome lined barrel such as this, and maybe that statement answers my own question, but would anyone suggest a certain 5.56 round count down range before using my CMMG .22 conversion BCG?

Here are some photos of the completed rifle, I know they aren’t that great since they were taken with my phone. This is my first build and my first rifle ever.
