Did you need to or did you choose to lap the bolts into the receivers at all when headspacing?

The last dozen or so Bula receiver/bolt combinations that I have put together required no lapping to get equal contact on both lugs.
Just in case you are interested, a bunch that I used chrome lined barrels on headspaced right at 1.633 by just indexing barrels.
Jeff at Bula really pays attention to keeping right to the center of spec.
Not so with any other mfg I have seen.

002 and 003 function fire only. Front and rear sights centered with 8 clicks of elevation. ZQI 20rnd mag dumps very rapid fire. 002 on left and 003 on right.
I did pay a little more attention to the sights after recoil on 003. At least they were all on paper at 100 without any hunting from the get go. I like Bula stuff.
