I done loads of work on this and made a few hammer variants but a well set up standard external power hammer was still the winner. Youd be better off looking at the issue youve got and finding out why. It wont be because steyr have designed it badly itll be something thats at the end of its life. A serviced steyr will give an 8fps spread with all standard guts. Do you need better than that? However if youre like me and like to tinker then ill be watching the "steyr hybrid" thread with anticipation, hoping you found the elixir.
