Things I liked: I have rebuilt 4 times now with this spring and find it to work and last longer than the original spring that came in the HW97K.

Things I would have changed: I wish that the springs came already polished

What others should know: Be sure to polish both ends of the spring before installing it

Things I liked: Everything

Things I would have changed: Nothing

What others should know: New spring is a different design than the original one. Original spring has a helper spring 2 inches long on one end. Looks like double coils on the first 2 inch section of original spring. My Beeman R10 with this spring and new seal, fires 10.65 Kodiaks at an avg of 770 fps. I added two hardened washers at the rear of the new spring before assembly. This rifle has absolutely no spring (twang) when firing. NICE.
