Fusion rifles like susanoo,vortex,vacancy, and phanta rhei! Long far gone isn't bad neither! Trust me. Even without the perks. U can one shot them at a distance before they get within rangefinders range. Tested and proved. Just make them come to you. They are over agressive most of the time. The fusions even best out universal remote. The long far gone is in the vanguard weapons master. Pretty good roll I'd recommend that then infuse it. U still gotta deal with the snipers tho.
