If I may throw my .02 in the ring;
Is there a possibility of a mil-spec bolt carrier to accompany this upper without the FA notches?
This upper/BC combo is something I searched long and hard for with no luck over quite a few recent upper builds. I saw the Les Baer option, and Youngs BC, but I don't trust the LB AR parts, I have not been impressed slightly with any of them, and I did not want anything other than a mil-spec, new carrier, without notches.
Thanks for listening to your customers Ranier, this is one of the only industries where that still happens.
