American Eagle Rimfire Suppressor rounds perform to their ballistic peak in suppressed firearms, thanks to carefully selected propellants, bullet weights and primers.

In addition, special clean-burning powders minimize fouling while reliably functioning in semi-automatic firearms. Suppressor loads are priced for volume shooting.FeaturesBullet weights and profiles carefully selected for suppressed firearmsClean burning powders for easier cleanupSubsonic muzzle velocitiesReliable function, feeding and ignitionFederal brass cases
