Set of AOE spacer pads AEG piston weight gain - 0,5/1,0/2,0 mm

Special heavier spacer pads for piston head AOE correction and piston load correction - set of 0.5 / 1.0 / 2.0 mm thicknesses.

A spacer pad for AOE (Angle-of-Engagement of the piston gear) correction with increased weight for piston loading. Suitable for DMR and similar builds where higher power (2J+), heavier ammunition (0.36g BB+) is expected. It is also a prerequisite to have enough air in the cylinder in proportion to the barrel length.

• In 3 different thickness options – 0.5 / 1 / 2 mm
• Individual pad weights:
• 0,5 mm - 1,1 g
• 1 mm - 2,2 g
• 2 mm - 4,4 g
• Made from brass
• Made in the Czech Republic
• Package contains 3 spacer pads - 1x 0.5 / 1x 1 / 1x 2 mm thickness

AOE (Angle Of Engagement)

The Angle of Engagement is an 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.

In pistons with metal toothing, this can lead to complete breakaway of the tooth. The correct AOE adjustment significantly increases the lifetime of a piston. There are two ways to perform AOE adjustment – by placing a washer under the piston head, or by using a thicker impact rubber pad on the cylinder head. Both methods move the piston towards the spring guide, lowering the teeth AOE.

In general, using the thicker impact rubber pad is the better solution. With a thicker pad, the impact of the piston head is more damped and there's no increase of the piston's weight, which would otherwise lead to increased wear of the gearbox.

If, on the other hand, an increase in piston weight is desired (for example in DMR builds - higher power and higher BB weight), a spacer pad is the easiest way to adjust the weight.
