The quality of the machining simply cannot be overstated; every surface is flawlessly smooth and finished to perfection. 

Not content with making an absolutely beautiful gearbox from the finest materials around, the team at RetroArms has also put a lot of thought into the design aspect, improving on the original Tokyo Marui V2 gearbox in several areas. The piston tracks and selector plate rails have been redesigned for wider compatibility, the front of the gearbox is enlarged in every dimension to improve strength, "glue pockets" have been added around each bearing hole so they can be glued in and wider internal wiring routes for heavy gauge wiring, along with much, much more.

  • Alloy construction
  • Reduce stress on your gears
  • More consistent FPS

The Bolster Armouries AOE Correction Washer is the perfect easy upgrade for your Airsoft AEG. It fits behind the piston head and ensures your replica has the perfect angle of engagement. This is the angle at which the first tooth of the piston toothing comes into contact with the toothing of the sector gear. If the AOE is incorrectly adjusted, the piston guiding rails and the first piston tooth are subjected to increased wear.

The correct AOE adjustment significantly increases the lifetime of a piston, it can also reduce the chance of your Airsoft platform jamming, which often occurs when the angle of correction is not correct. The FPS will also be more consistent due to a smoother and more precise engagement when firing the AEG.

Treat your Airsoft AEG to the Bolster Armouries AOE Correction Washer and watch as its performance becomes more consistent and the piston survives many more skirmishes.
