I'm on the hunt for a suppressor cover for my SilencerCo Specwar 556K. I use it more on my primary fighting rifle than on my SPR. That said, I'm trying to find a good cover that will hold up to some semi-rapid fire use more than just a few slow strings to avoid mirage like on a bolt gun or SPR. I'm currently looking at either a TAB Gear, SilencerCo, Rifles Only HAD, or Armageddon Gear. Hoping other can owners out there might have some first hand experience. Let the suggestions fly!! Thanks!
