Thanks! The entire build has been an ongoing process since close to the beginning of the year. So much planning goes into making each piece as well as making sure each peice fits with all the other pieces. As for the trigger assembly and guard, it took a day or so to make/find all the individual parts, but longer than that if we're talking about designwork.
At this point, I make this content as a hobby, but would love to make enough money to do it professionally. Sorry for the late response. DTube wasn't letting me respond to comments.
