The 'Pulse Rifle' got me thinking.

It shouldn't just be a gimped ScR...
It should have a defining feature, something unique.
So, it should be a 'Tactical Shotgun'.
Semi Automatic, Great DPS, Short Range with harsh falloff.

Stats:

Damage per laser: 51
Lasers per shot: 5
RPM:120
DPS: 510
Effective Range: 25m The damage dropoff is harsh, only dealing 30% at 30m and 10% at 35m
Rounds per magazine: 18
It does 120% damage to shields, and 80% damage to Armor. As expected.

It has a somewhat tight hipfire, slightly tighter than the ARs hipfire.
The lasers always fire in the same pattern, because they are lasers.
The pattern looks like this:

X...................X
.......................
...........X..........
..........GǪGǪ........
X........GǪ........X

Possibly this:

..........X..........
...GǪ.................
X........X.......X
......................
..........X..........

The pattern tightens slightly when the trigger is pulled, and after about 8 shots(4 seconds), all the lasers are focused on a single point. It will overheat in 10 consecutive shots, making the last two shots before overheating very powerful, but fairly difficult to land.

Its appearance is that of an ScR without the blade-like cooling apperatii on the end. Instead, it has a sort of beam-splitter at the end of it, a small device that looks somewhat like a shotgun choke. The optical sights are removed on this weapon, and iron-sights are the means of target acquisition.
