6.03 mm - 129 mm precision barrel for AAP01
Action Army AAP-01 Precision Inner Barrel – 129mm, 6.03mm Engineered for AAP-01 GBB pistols, this tightbore barrel tightens tolerances to stabilize BB flight and reduce wobble. The 6.03mm bore constrains projectile movement, maintaining velocity retention and improving shot grouping downrange. Electro-chromed brass construction with a polished interior minimizes friction and wear. An integrated o-ring cutout at the muzzle provides additional stabilization. Unbridged design fits stock and CNC upgrade hop-up chambers with GBB/VSR bucking compatibility. Optimal performance depends on hop-up quality, ammunition cleanliness, and proper cylinder-to-barrel air volume matching. Select length based on your replica's original barrel specification.
