FPS HOOKING ANGLE ADJUSTMENT SHIMS (SAOE1)

Set of three shims to be interposed between the piston head and the piston to modify / adjust the engagement angle between the first tooth of the piston and the first tooth of the sector.
The insertion of these shims causes a slight retraction of the piston and decreases the engagement angle.
This procedure can increase the reliability of replication.
When passing from a standard engagement angle (MARUI type) to a non-standard one, it is advisable to make the necessary modifications to the piston (elimination of the second tooth and possibly reduction of the third).
If you are a beginner, it is advisable to contact technicians with proven experience.
A normal piston head can withstand a maximum thickness.
