A replacement or upgrade air nozzle for Airsoft electric SMG-5Ks.

FPS Softair brings us a Carbon Fibre Reinforced AEG Tappet Plate for use with version 2 gearboxes. It is specially formulated to be strong yet flexible enough to bend slightly.

The plate is constructed from extremely lightweight polycarbon and is designed to be attached to the air nozzle and sector gear. This process controls the feeding of BBs from the magazine into the hop up chamber.

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.
