Fully CNC machined Duraluminium gearbox shell for all Version 3 type RIFs. 

Retro Arms make arguably the strongest gearbox shells in the world so if you want something basically indestructible, look no further. 
These gearboxes take all standard fittings and come with T10 Torx screws.

Retro Arms CNC Gearbox V3 AK (8mm) - QSC

Out of Stock
  • Takes 8mm bushings or bearings. 
    Compatible with the vast majority of V3 RIFs however some modifications to the receiver or gearbox shell may be required in some brands. 
    We don't recommend these for G&G AKs due to their non-standard design. 

    We recommend all surfaces that come in to contact with moving parts be lubricated with Superlube PTFE grease. 
    All screws should be secured using Loctite 266 thread lock or similar upon final assembly.
