GTA Online · QUICK ANSWER
Best sniper for your GTA Online loadout
Our main long-range upgrade pick is Heavy Sniper Mk II. Regular ammo is a practical default for player fights; the regular extended magazine holds eight rounds, versus four in special magazines. Thermal Scope requires Bunker research. Explosive ammo is a specialist vehicle-combat choice, not a guaranteed one-shot player kill.
Consider Marksman Rifle Mk II if you prefer its sight options and larger regular magazine. This is a role-based recommendation; range, hits, armor and boosts affect outcomes.
