Equipped with a Navy-style grip assembly, ambidextrous selector switch, and standard G3 trigger setup, the AP51 offers intuitive control and tactical versatility. The birdcage-style flash hider, Magpul BTR brace, and wide MP5-compatible handguard round out a feature-rich platform that’s ready for duty or defense.
