hi
someone gave me one of these years ago,its around somewhere after a house move
I remember it looked seriously fragile to go on a recoiling springer.
Is it worth finding to put on a HW35??

Ive never had any problem with loss of zero while using one of these on a variety of rifles including the '35. I wouldn't class them as fragile because there is a screw to lock the locking screw !
