apologies for the late bump, but work's been busy

as it turns out there doesnt seem to be any local gunsmiths around, and this is really bumming me out. i'd not like to have wasted 150 on my stupidity so ill figure out any way i can

here's another screenshot this time from the magazine tube hole, but detached. if anyone knows what redlining is (circling an area that the problem is using an image editor in a red line), using these two images could you perhaps see what needs to be fixed if you have a keen eye? this is super beneficial to me and at this moment anything i can do to at least get to be able to cock the bolt would be wonders.

now when the stock is off and the trigger is down i can move the bolt/pump back slightly because i can press in the manual pump button near the trigger. but i cant when its fully straight. im starting to think something may be blocking or stopping the button from being pressed in now, perhaps a jam between the cracks or a tiny sliver of the plastic from the snap cap's edge came off. anywho, any help is always appreciated
