You need to stack the deck in your favor when you don't think you can win an aim battle just like you would with a weaker weapon. Shoot them in the back, blind them with a flashbang, catch them in a crossfire, fight from heavy cover, hold a difficult to predict position etc.
Most importantly, don't stop moving unless you're hiding or have a strong position. You want to be the one getting the peekers netcode advantage.
