Mass Effect 3, M-13 Raptor won't fire

Hey guys,

So I thought I was going absolutely crazy, because there's an issue with firing my sniper rifle. I'm currently running the Tuchunka: Turian Platoon Mission. I was running through, got to some bad guys, whipped out my M-13 Raptor V, zoomed and hit R1... nothing. Switched to all my other guns, they fired just fine. For some reason just the Raptor is not firing. There's no message, never thought the guns could get damaged... Anyone experience anything like this before? Sucks being an infiltrator with no sniper... 😕mileymad:

Thanks
