In general, the G3SG1 has the features of all sniper rifles in CS2: low accuracy in the unscoped mode, decreased movement speed, high damage, and easy kills when scoped in. The G3SG1 is exclusive to Terrorists, and it’s a direct counterpart of the SCAR-20. The weapon has an automatic fire mode, which is compensated for by lower damage compared to bolt-action sniper rifles AWP and SSG 08. It’s an expensive gun and a dubious choice for competitive play.
