    The fit and finish of this muzzle device is excellent. It works well and keeps the flash away from the shooter very well, even on short barrels. I recommend this product

  • Does mitigate initial blast

    These Kaw Valley comps are doing the job! I have them on my 9mm carbine, 556 and now 300BLK rifles and in each case do direct sound away and mitigate side blast when you have folks shooting to your left and right. This 308 version is smaller than my 556 version but surprisingly does as good a job. It is made of steel so should last a lifetime. Also I used a bit of Rosksett to secure it.
