Had mine about ten years now!
Trigger position can be helped with (I think) a Rowan set back trigger. I think that's where I got mine.
Next I fitted a V-Mach kit. If you get the power down to about 10.5 things smooth out nicely.
Mine is a .22 and I think that is an advantage with this rifle.
No problem with scope mounts providing you use an arrester pin.
I previously had a HW95 which out of the box I found truly horrid and just couldn't get on with. Much prefer my 57 - but agreed I'd only use it for 25 yards, but that would be true for me with any springer
They are a bit different, and BAR did them no favours but they have a place in my heart!
