After reading the What is it about the 80 thread I decided to get mine out and have a blatt. This particular one is 22 & now has a 20mm shorter stroke plus buttons etc running at 11.3 with falcon accuracy plus. The big thing I noticed after shooting my 22 Diana 34 is how noisy it is. Not mechanical, just goes with a crack despite a vmach steel silencer v the unsilenced Diana in k form. I was wondering if this is to do with the stroke. Its fairly stable on firing and consistent, could it be the piston coming to rest quite sharply? It has one of the new HW seals fitted. What do the tuners think?? To me the Diana is much more pleasant.
