.308 muzzle break
 

What is a good muzzle break for a .308 that will not blow debri back at you when shooting prone?

A 308 is a relatively light kicking cartridge. A think a muzzle break would not serve much purpose except create excessive noise. Not sure good brands.

check out Brownell's or Midway as both have good selections of muzzle brakes to fit a 308 that might suit your needs.

Kdub, sometimes people want one when shooting prone so as not to blow dust up when fired. they also function in that capacity as well as reducing recoil.

Fair enough.
