Hi I was wondering about the Hobbyfix line of rifles, like the Hobbyfix m16a1, m4a1 and so on. Are they able to fit real furniture? How much are the Hobbyfix m16a1's worth? Are they realistic in the aspects of disassembly and function? I believe I saw a video of someone in Japan cycling shells and using mags. I read here or somewhere else that they're able to take real steel mags and rounds. Are they able to take furniture too? Like stocks and handguards. Thansk!
