Now that you mention that, I think I'm wrong because I remember thinking my RAP was a "cock on open" because they're hard to judge bolt lift or sticky at the top of extraction because they click naturally when cocking. Maybe it works the same on both designs?Thanks for chiming in I believe nearly all bolt rifles really behave this way now that you mention
If your bolt is even slightly open, the firing pin's cocking piece will force the bolt down as it travels forward, losing a ton of energy in the process.
Please excuse my ignorance, my ECM board for my HVAC fan motor went tits up and it's currently 80° ambient in my living room so I'm trying to occupy my mind while sitting here sweating..
