I installed a SSS fluted bolt body tonight that I bought from a member here. I installed the bolt and noticed that the rear baffle ball slot was indexed a bit differently, then noticed that the bolt would only rotate about 60 deg.

I dis-assembled it and found that the cocking ramp was in a different position radially relative to the two bolt handle ears at the back of the body compared to the original Stevens 200 bolt body.

Any ideas what's different and why?
