DM8 Quack

[Bigste Shogun]

My Dm8 is making a quacking noise most of the time its firing, i was having drop off problems but have sorted that out now witha combo of LPR/FPS and dwell. Since those fiddles its developed this quack.

anyone experienced it before or any ideas? bolts lubed

thanks in advance
