The Lok bolt is a great mechanism, the spring is tiny and a pain to get on correctly, but after a few tries it does go on, hopefully it doesn't get lost or come off because it does... view moren't look like it's being held on very well, I might have to try and glue it or some type of mod to have it stay on/in the Lok bolt mechanism.
