  • Retro Arms Gearboxes are manufactured from one block of aircraft aluminium (Dural) EN AW 7075 T651; they are milled on multi-axis CNC machines.
  • For comparison, the strength of aircraft aluminium (Dural) EN AW 7075 T651 is 550MPa, common construction steel has only 390MPa.
  • All of the gearboxes are designed for the best durability, resilience and strength on the most powerful springs.
  • These gearboxes are designed with full Tokyo Marui compatibility in mind.
  • Includes bearing bores for 8mm bushings or bearings (not included).
  • Package contains gearbox shell, spring guide and all necessary screws.
  • Suitable for Tokyo Marui NGRS Recoil Shock rifles.
  • For TM NGRS 416D
  • For TM NGRS 416C
  • For TM NGRS 417
  • For TM NGRS M4

2024 Version Gearbox Case:

  • Reinforced the integrity of the gearbox around the pistol grip.
  • Enlarged the holes for cables.
  • Enlarged front hole for cables for 416C compatibility.
  • Better cable routing around motor axis - added groove and nose as on V2 gearbox.
  • Improved bearing bore drilling - more accurate bore and larger tolerances on bearing diameters.
  • Enlarged grooves for the switch backdrop.
  • Enlarged cylinder bore.
  • Redesigned cylinder bore relief - created for maximum strength.
  • Redesigned cylinder mounting on 4 support points instead of full length - greater compatibility with multiple manufacturers.
  • Enlarged piston groove for increased gearbox life.
  • Edge removal - previously a cable routing issue.
  • Removal of radius - previously a problem with bolt movement.
  • Reinforcement around the cylinder in the rear.
  • Spring guide together with mech box in package to ensure full compatibility with retro arms piston.
  • Installation of the inner parts and gearbox requires professional knowledge, experience and skills. There are a lot of airsoft manufacturers on the market and every one of them create their own sizes, there are no standards like engineering ISO in airsoft.
