(continuing from last comment)
Besides, in the time it was manufactured, 2034, technology permits me to implement specific features to this gun.
(No offence intended, though.)
To answer your design standpoint issues...
1) There is a channel cut through on the rail systems. Otherwise, it would defeat the purpose of having iron sights.
2) The reason I implemented a DA/SA switcher is to accommodate the use of subsonic 5.56mm tranquilizer ammo made by GR. By switching it to single action, it will greatly reduce the noise generated when equipped with a suppressor. (Think of this SA mode as the Mk. 22 in MGS3.)
3) There are regular (22-round) and government-restriction (10-round) compliant magazines designed for this gun and its other models which fit very snuggly in the grip. (Like the FNH Five-seven.)
As for the other issues, I will keep that in mind for future models.
Forgot to mention that it is also ambidextrous.
