Things I liked:

Its great that pyramidair is selling these original German piston seals for the RWS / Diana rifles , the quality is excellent. Having these parts available at a reasonable price is a good reason to buy from pyramidair.

Things I would have changed:

Absolutely nothing.

What others should know:

In my honest opinion and from experience I believe that the best piston seal for RWS/ Diana rifles are the OEM ones blue like the one object of this review. These seals last a long time and they produce the power the rifle was designed for. Thank you pyramydair keep up the good service

    i need a seal and spring for a model 45 s/n 682095 will this work ?

    • steve'sdental lab from USA answered:

      Yes it will work but first you have to do the leather to this type of seal conversion. You can get the kit and spring for the gun at vortek products the spring you want is part number 820128-33k Here is a link to the conversion part
