This is a minor adaptation to my existing tac build. Just swap Back Pack for Ninja-bike and any two other pieces for firecrest.
You can see my tac build here: https://division-builds.com/build/4171-bog-standard-tac-seeker-sticky
You can consider using Tech Support instead of Critical Save.
This build does more turret damage than Firecrest as the skill power is higher with stacks, it is also more comfortable for tac players.
Please note the Assault Rifle's are crafted from 204 level blueprints, Any 204 level assault rifle will work but LVOAC is best.
When sending out seekers use main weapon and when shooting though's burning mpc's use secondary to proc talented predatory and sustained.
It is very easy to stack and get kills with weapons as the mpc's are burning and not shooting you.
Skill power with both 30 stacks and talented is very high.
The flame turret seeker combination is a devastating combination with this build.
remember this is just a guide make it comfortable for you and your play style.... enjoy
