[PDI] Power Adjuster / for Bolt Action

The power adjuster is a fine-tuning ring made of POM that shortens the space inside the piston and strengthens the spring tension.
Like the thrust ring, it also prevents the load caused by spring twist during cocking from being transmitted to the piston.
PDI large diameter piston compatible with all types

It is inserted inside the piston head to provide spring tension. It has a hole in the center so that it can be used with vacuum system pistons.
When installing, there is no need to disassemble the piston; simply insert it from the rear.
*The use of multiple sheets is not recommended.
