Pioneer Arms Sporter 5.56 AK 715 Round Review and Accuracy Testing
This review of the Pioneer Arms Sporter 5.56 AK details accuracy testing at 100 yards with various ammunition types, revealing significant inconsistencies and flyers. After 715 rounds, internal inspection shows some peening on the bolt and trunnion, with a notable mushrooming issue on one bolt lug. The rifle appears overgassed, indicated by brass marks on the dust cover, though the muzzle brake effectively manages recoil.
