My planned three AC/10++ Annihilator just changed to a three Gauss Rifle Annihilator. More Stability damage, less threat of ammo explosions, longer range, all I have to do is give up some ammo, a little armour, and the secondary weapons. If I can get my hands on some Gauss+s that'll recoup all bar the secondary weapons. Assuming the internal damage is affected by neither the Annihilator's system nor damage reduction, that's three headshot chances through 40% damage reduction! If the internal damage is affected by both, it'll still well and truly headshot 20%DR, and only be one tantalising damage point short of headshotting through 40%DR, just like a stock AC/20 on a non-Annihlator platform would be. The only problem will be if the enemy gets under my range, but that's why the Annihlator will be mounting JJs.
