Quoting Chris K
Pretty good, but it could use some work. I would suggest making it bigger and a little more like the shape of an AK-47. It is a good start, (my first gun ever probably looked worse) and if you keep building guns they well get better. Maybe all you need is some inspiration! The more experience you get the better your guns will be!
You're right. It looks a little more like the AK-74. I'll try something different next time.
