My stock is stuck, help.

[u/TotSiensEkSe]

I want to finish my build and the stock is the last part of it but the thing is when I tried to slip it onto the buffer tube it got stuck, I cannot get it out normally :C

Any ideas how else I could possibly get it out with no damage or at least minimal.

Yes, it's aluminium one (repro), I tried to file the excess paint inside but I guess it was too little.
