Ugh. I hate it when people who don't know anything about weapons try to draw them realistically. Either make it intentionally cartoony, or learn the basics of what you're drawing, y'know?
(Did I feed the troll right? Or did you actually not read the description. In which case you're excused, because everyone knows the average internet browsing person's attention span is 6 seconds at most)<small>
Usually I look up some reference of actual weapons, but as it says in the description, that kind of went to the backseat in this exercise. The focus was on Applejack's anatomy.
