It took me longer than expected to to interruptions and getting dragged out, so on the laptop. Now, where was I…
Now let’s see, full-auto-only weapons, and their stated rates of fire in case that becomes relevant:
M249 (800 RPM according to wikipedia, 850 according to FM 23-14, 650-850 according to FM 3-22.68)
Mk 19 (325-375 RPM according to wikipedia, same according to FM 3-22.27)
And a few cases of harder to figure out weapons:
Briefcase SMG I would assume is based on either the Uzi series or the MP5, both of which are selective-fire.
TEC-9 is normally a semi-auto-only pistol, based off the earlier MP-9 SMG. All info I could find suggests that the only full-auto versions of the TEC-9 itself were illegal coversions, and presumably would not be selective-fire.
Calico M960 comes in both semi-auto civilian versions and full-auto LE versions, can’t yet find info on whether the full-auto version is selective-fire.
Rivtech RM451 is, as with non-fictional flamethrowers, likely going to discharge its fuel in streams, so likely should also be treated as full-auto only.
Rivtech RM360 seems to be bastard love-child of a Gatling gun and an American-180, which is apparently seletcive-fire, so we can assume the RM360 is too.
Rivtech RM614, being a fictional LMG, is likely full-auto-only, whereas the LMG variant of the Leadworks L523 Platform likely retains the same fire control group as its other variants.
Rivetech RM298 HMG presumably is full-auto-only and comparable to the M2 Browning.
