Actually I don't have both of the kits, but after seeing both kits manual maybe I can give you some idea(don't know if it works though...sorry
). First of all, maybe I gotta point you to the instruction manual for the beam gatling gun:http://dalong.net/review/mg/m102s/p/m102s_m2.jpg
for the problem, i think what you can do is to take off q11(or maybe you don't need to, try both
) parts from beam gatling gun right. Put the shield at the usual slot, connect both beam gatling gun using the upper connection and put the beam gatling gun left at it's usual port( front one).... Hope it... works??
Anyway, Some extra observation from the MG FA Unicorn
booth pics seems indicating that the kit will have a special extra attachment to put the shield into the beam gatling gun (replacing the Q11 parts and connecting the beam gatlings, compare it with this picture
.)-the extra part seems effectively eliminating the I 22 +I 27 + I 24 parts from MG Unicorn Shield.
