Semi S5 spring question
Recently bought a used s5 autococker. First thing I did was re-lube the gun and sweetspot the reg. I had difficulty getting the gun to shoot higher than 275 fps. I also noticed, while playing over the weekend, the gun seems to be a bit inefficient.
I might toy with some stiffer springs to see if that'll make it more efficient and shoot closer to 300 fps. Maybe a madman blue valve spring with a green main spring.
I know it's a big no-no to mess with ccm lower tubes but I figure I don't need a light pump stroke since it'll stay as my main autococker.
Just wondering if you guys think it'll fix my problems or did I not setup my gun properly? Any input will be appreciated. Thanks.
