The box of bits arrived today and in about an hour I had it mostly together. I didn't bother doing it 100% as it's coming apart soon to get completely rebuilt. It's scruffy and there are some fitment issues in a couple of places and a couple of bits missing but nothing that can't be fixed. Overall I'm really happy with it, it was cheap, it's lightweight and when it's done it'll be a good reliable backup or loner gun
