Any break would work better then an A2 flash hider.
No,,,, This is a very good muzzle break, and it would work great on your rifle if it was chambered in 6.5 Creedmoor, but your rifle is a 30 cal (7.62mm) this break is for a 6.5 mm barrel. Ultradyne does make the Apollo S in a 30 cal version, but it doesn't look like Optics Planet has it listed.
