I wish it just seems to be stuck on something but can't seem to figure out what i've tried depressing the spring i've tried brute forcing it out i've tried prying it out im at the stage of just getting a saw blade and a drill and buying a new one...
no no no no no.....
undo all the pins grip n stuff and it will free up loads of slack
undo stock tube, receiver pins and pistol grip if still no joy
you haven't got the thin gearbox pin in there at present...
but in your 2nd pic (I cropped it and zoomed in it btw)
in your 2nd pic the thin gearbox hole looks out of whack/alingment
Have you screwed on the stock tube ultra tight and yanked the box right back to get that mag catch to rub so far forward that it wedged itself in there when incorrectly fitted???
you should be able to free it all up once it has some slack in there.....
the refit should go something like this:
receiver pin & thin gearbox pins
pistol grip - ensuring the grip doesn't pull the box out - if so a bit of filing on grip needed if it pulls box out of whack
actually it usually pulls the motor alignment out of whack than the box itself but suppose it could try to pull box a whisper back
then stock fitted after this and check it doesn't pull the box backwards & possibly up a little....
if this takes place it usually means a small gap is at back of gearbox & receiver - fit a piece of rubber or something to fill that space
normally on polymer receivers a small 0.5mm to 1mm gap it will be ok as the receiver will give a bit
on full metal receivers it won't give and will simply try to pull box backwards and sometimes upwards at nozzle
this can cause the nozzle to rub in hop unit and create bad sealing
check box is straight in lower receiver and if pulled up/back a gap can appear where trigger is mounted out of box in receiver
damn I need to get out more if I now waffle about gearbox/receiver alignment so much
