Hi Guy's, my first post and I'm sorry if this has been covered before but what internal difference is there between the 1996 mk1 ps and my current 2004 model? Thankyou guys. Kt83

As far as i know the early ones had a shorter stroke 82mm i believe.
The newer ones are longer stroked at 96mm I believe.
Other than two extra side stock screws,on the later ones.
And different springs.

The early pro-sports had plain stocks, and no extra screws at the rear side of the stock.
The spring had three closed coils at one end, the cheek peace was lower and less profound, the stroke was shorter, cylinder diameter was lager.


The later pro-sports had lovely lazer checkering higher cheek peace and upgraded cocking lever linkage. the spring was up graded and so was the tx200's,,
cocking stroke longer and the piston seal.. ect was upgraded to a smaller diameter.

Air arms changed the size of the piston seal in the year 2000.
