What's changed from the Lightning assault rifle?

Extended barrel
Smaller mag
Changed trigger and trigger guard
Cheek rest on stock

A few tweaks

Why did you change it into a sniper?

For four reasons

1) extra accuracy
2) I needed a sniper for a war
3) because it looks cool
4) because I can

The same as with the Lightning except the mag capacity (5 yellow rods)
