My 6mm arc is almost complete, waiting on ammo.
The 6.5 g ended up needing an H1 buffer and flat wire +10 % spring from 223 set up to run right.
I opened up the agb on my 223 upper 1/4 turn after the lower mods and all was well again for it .
Stands to reason if you were set up for 223 that those two things will help .
