I measured the dimensions of my spare Anschütz Stabilisator. Anschutz uses the same type of shot reaction absorber as the one that Steyr developed for their LG100 and LG110 rifles. The Stabilisator is used in the Anschütz 8002 S2 and Anschutz 9003 S2 air rifles.
The advantage of the Anschutz Stabilisator is that it can be adjusted for travel distance from the outside, without having to disassemble the rifle.
The Steyr Stabilizer body has a lenght of 94.48mm, which is 16.94mm longer than the Anschutz Stabilisator body of 77.54mm.
Part number 200 is the spring (0.90 x 3.6 x 20.5mm) that drives the Stabilisator mass (Part 205) backwards.
Part no. 201 is the adjuster that sets the protrusion of the spring 200 .
Part 202 is the friction ring that brakes the Stabilisator.
Part 203 are the 3 springs.
Part 204 is a Perlon safety pin (2x8mm).
The older type S1 Stabilisator was slightly different:
