I attached an ammo mod to my Barn Buster Top-Notch RL. Now when I shoot, it sounds like a detonator shooting. I can't remember the name of the ammo mod (sorry, I didn't look before attaching), but it adds shield penetration. This probably doesn't matter, but I'll mention it anyways: the ammo slot was locked and I had to unlock it. Doubt that's part of the problem, but who knows.
