AR9 Firing Pin Spring Washer?
I'm attempting to get an Atrius Forced Reset Selector working in an AR9 build. I've tried the Amazon special spring, but seemed to be giving me light strikes after 1 round fired. I know the next recommended step is a titanium firing pin, but could I just put a washer or two on the firing pin before the spring to give a little more preload on it? Should I be worried about the washers somehow causing damage in my bolt? What are the chances this gives me light strikes all-around?
Total bolt/buffer weight is pretty light at about 19-20oz. I'll be working on upping the weight, just troubleshooting the FRT at the moment. My buffer does have deadblow weights, and slow-mow videos show no bolt bounce, which makes me think its a firing pin momentum issue. Also, I did trim the bolt weight to accommodate the lever.
