Action Army AAP-01 CNC Hop Unit
A high grade, CNC hop unit for the AAP-01 gas blowback pistol. These are a fantastic improvement and upgrade part compared to the stock hop unit. They are easy to assemble with the included instructions and much easier to adjust than the standard hop unit.
They take standard GBB barrels and hop rubbers and now feature a ‘clicky’ adjustment wheel to ensure a consistent and stable adjustment. #
Please note: the inner barrel is not included and is for illustration purposes only.
