For anyone reading, AE is great. Answers all my questions, genuinely wants to help me fix my gun.
@rocketdogbert you are also awesome. Thank you so much
i did sand it down to clean up some of the imperfections, will shoot a few bb at lower FPS and weaker blow back then jam or shoot 2 Bb then the bolt gets locked back.
Even with some dry fire, at times, the bolt locks back as if I was out of bb
