I've been thinking of sending ADCO my 16" HBAR upper half (hopefully late this year) to have it re-contoured to a semi-LW profile, .750" under HG, and .625" in front of FSB. (currently these areas are 960" under HG, and .720" in front of FSB!) but i was wondering one thing i did not see mentioned in the advice section for what all to send.

Should i send the BCG, or at least the bolt wih the upper half so you guys can check headspace, or send the barreled upper empty? what about the charging handle?

Thank in advance for any advice.

no need to send the bolt, we dont touch the barrel extension so none of that would change.

Wow, that was a quick response, thanks.
