I was seriously considering of picking 1 up considering I'm looking at some M4s. I too have the CA36 and a difference in the color doesn't phase me. What did deter me was that on AirsoftParts, it says with CA guns that it needed a "slight modification" but I couldn't uncover any details on that but hearing you had no issues has definitely put that magwell conversion back on the books.
Good review. Cheers.
