If you are right in that the 470 has 115mm stroke then its not the gun to get, the rifle to get is the 440, fit the 470 under lever and move the catch forward or make a new one..or do as i did and replace the rod from the underlever.

Is the rear action on the 470 longer than the rear action on the 440? The 440 will do 20fpe easy in .22 already in stock UK form with the right set up.
Tony,
It just has a longer action

Also the T05 -T06 trigger kit is the same with the same piston,
the T01 stroke is longer because it has a shorter piston rod.
