Ok to critique this I'm gona put out a pros and cons layout: PROS: Small/compact (I assume its small) so good for indoor combat with tight walls. CONS: Looks like you might have a hard time slipping your fingers into it. Reload could possibly be difficult (depending on your environment. What would make it good: A fire rate of 900-1000 rounds/minute. Yea I could see this doing good work with combat in a building. Small so you can maneuver it faster (When it comes to guns the size really does make a difference in how fast you can swing that gun around to the nest target). It'd be good if it did have a fast fire rate because when it comes to cramped halls your gona want to be able to squeeze out those 6 bullets faster than the other guy.
