I finally got all my parts to build my 300 BLK upper. I got it all put together, everything checked good. I bought a 16" recon contour, 1:8 twist Wilson Combat barrel. I've looked on their (Wilson's) site , but I can't find a break in cycle for the barrel. Does any one know, or have a good recommendation for break in of the barrel? Thanks for any and all help.
