I personally like the laser targetter BR with a sentinel scope. the bullet magnetism is bumped significantly (better than the 2BR) and the scope has two different zoom modes for mid to long range engagements. I almost never miss my shots with this rifle and have won a lot of warzone assault and regular warzone matches. as my secondary to that I am torn between the kinetic SMG and the laser targetter SMG. (PS I could be mixing up the laser targetter and the target locator) this loadout ensures that I will have every valley covered. long range, check. mid range, check. close range, check. bullet magnetism, check. and with kinetic bolts on the SMG I can go for more damage to vehicles as well as Spartans and AI.
