I run a similiar Setup on my Timber Wolf (except it has 3x cSPL instead of 1x cMPL) and because of the Couldron Borns Height you can make it a really good, but also little bit squishy, Brawling Machine. With the two cUAC/10 you can make a good Supportmech for Mid Ranges or just go right into the Action with it. Because the Prime Variant has only one Energyslot i just put a Med Pulse in here for the Range and Damage Bonus. But i am still thinking it would be better to just exchange the right Torso to "B" to actually mount 2x cSPL which should do far more Damage. Anyway this Setup is one that can wreak someones Day really fast! Updated Setup: Based on the Tipps i received and because of the Experience with this Build i placed the Ammo into the Ballisticparts of the Couldron Born and took half of the Armor away from the left Arm, its unused but now its used as a Shieldarm, and upgraded to 3x cSPL because a single MPL isnt really a Help in a fight. Now it is really a though Mech in Mid to Brawl Distances and packs a serious Punch for everyone that comes near it.
Putting both UAC10 in the arms really hurts the convergence of the ballistics because they are so far apart. You will always need to lead a moving target, so it's best to have them as close together as possible so the burst is tightly clustered, increasing your chance to hit with as many shells as possible. Another thing is storing ALL of your ammo in one torso is a horrible idea. You should spread a lot of that ammo into the arms (IF you run both UAC10s in the arms still). Here is my take on a 2x UAC10 build. You swap the LT omnipod to take more energy slots, swap the RT omnipod to move the UAC10 to. Now you can strip that left arm bare and take more stuff!
