Your custom Stormhunter doohickey guy inspired that gun, actually. I was looking at your picture and the color of the clone rifles stock almost matched the background of the photo, so I thought you had made a modification. Then I got to looking at shotguns online, and I saw some didn't have the stock on it, and they are generaly assult or swat weapons, so I decided to cut the stock off, and sand it to a curve, so it was like he had a special combat Republic Rifle, because he was once a security personelle for the Republic durring the Clone Wars. But that story is for another day.
The best part about that rifle is that he can hold it like a regular handgun, or hold it close for sharpshooting wamprats while visiting the sewers of Courescant, or attacking a speratist outpost somewhere in the jungles of Yavin.
