Forgot to mention this aswell. 
Gunned for someone who chose the 50 cals instead of the 30's. 
But upon looking at the guns, I found 6 barrels(quad 30's and 2 50's)
the 50 would traverse while the 30's stayed stionary. 
Will post pictures when I get home. 
Btw, happened only while gunning, and no when I upped my own lancs
