A former marine explained the purpose of a flash hider was not to keep the enemy from seeing the muzzle flash, but to shield the firer's vision from losing his night vision during low-light/night firing. If that be true (I do not know if it is...my issue M1 Garand in 1962 BASIC Training did not have one), then it would follow that a hunter would not likely benefit from a flash hider inasmuch as light that dim would not be in normal (legal), shooting hours.
It is notable that during night firing exercises with the M1 (no flash hider), in BASIC Training, I did not lose my night vision and scored quite well on the moonless 100 yard targets.
