BUT my AW15XX has the Thompson Center heavy barrel and no problems.. so it's a certain run of them that are suspect, not all. I am getting 2 MOA with everything and irons or an EotechAW 2000 to AW8000 have heavy barrels, tight chambers and do not cycle tar sealed ammo. No Radway, DAG, South African or Portugesse surplus in these,
but my AW35xx and AW53xx, both shoot 3-4 moa groups with steel cased Wolf and Tula, better than 3 moa with Remington 150 grain Core-loc.
yes, 5 round groups, at 100yards.
