I don't think it is allowed. But NRBH, What does A7.55 say?
I completely agree that this problem is left unclear in the RB and a question to Perry is warranted. I am not sure what about A7.55 makes you favor the opinion that you couldn't BFF a CMG, expend a delay MP, and then fire your BMG at the same target (so long as it doesn't leave the hex, violating D3.51). Because of the delay point, the shots are clearly not "simultaneous."If Good Order units/weapons in the same Location are going to fire at the same target (i.e.,, at both the same Location and the same unit and the same "simultaneous" [8.1] MF/MP expenditure; see D3.5) during the same phase they must form a FG.
On further consideration I think the weapons must be combined, even if fired on separate MP expenditures.
D3.5 "The FP of a vehicle's various MG/IFE armaments may all be added together for one attack (assuming the target lies within their respective CA), or fired separately at different targets [Mandatory FG (A7.55) applies." This says to me that you can either fire at one target as a FG or fire at different targets. There is no option to fire separately at the same target.I completely agree that this problem is left unclear in the RB and a question to Perry is probably warranted. I am not sure what about A7.55 makes you favor the opinion that you couldn't BFF a CMG, expend a delay MP, and then fire your BMG at the same target (so long as it doesn't leave the hex, violating D3.51).

I assume that you are ignoring the parenthesized portion of A7.55 (as cited) since it appears to refer to the target's MPh. However, such rules are often reversed when using Bounding Fire, like the modifiers for "limited view" (Cases J1/J2 become C1/C2) now apply to the firer's MP expenditure, and that a MA must expend an additional MP before taking a second shot rather than waiting for the enemy to expend an extra MP/MF instead.
Likely true, I would say. And D3.5's reading is persuasive enough, JR. Particularly since it makes no mention of MP expenditure. However, when you next read D3.51...I am pretty sure the "simultaneous" - only refers to a target spending MF/MP in the MPh. Since a BFF is not tied to a MP expenditure.
Not unless you want to use the firepower in the attack.If mandatory FG applies, if one weapon is outside the .CA, do you need to turn it to bear to fire it at the same time as other weapons?
So I can go up, with my turret away from the target. Stop. Fire BMG. Delay and turn the turret, fire CMG?Not unless you want to use the firepower in the attack.
Note that during the friendly MPh CAs do not change as part of a BFF attack. You must make any CA changes you want as part of movement expenditures.
You can turn (delaying if necessary) and fire. It's not clear why you didn't turn your turret when you spent the MP to stop, which in most cases you just did. But perhaps you fired your MA in another direction. In that case you would have to delay and turn your TCA.So if my turret is facing away, I have to wait to fire the BMG with the turret having been turned to link up or I cannot fire the CMG at that target?
