AA CNC Outer Barrel Connector AAP-01 - Black This CNC aluminum outer barrel adapter for the AAP-01 repositions suppressor mounting directly behind the pistol frame, eliminating gaps and enabling G-Spec-style configurations. The 14mm CCW thread accommodates standard suppressors and barrel extensions, while support for AEG/GBB extensions facilitates concealed inner barrel routing through conversion kits or extended handguards with RIS/M-LOK interfaces. Precision-machined from lightweight aluminum for durability and reliability in extended use. Designed exclusively for Action Army AAP-01 GBB platforms.
