Great sound attenuation alternative to a break - V Seven Helios Linear Compensator

I recently purchased the vaunted POF Revolution in .308, and by the way, a fantastic rifle. One of POF's claims was the recoil mitigation and muzzle flip reduction with their 3-port break. Well, it performed as advertised, but under the bench roof cover, at my range, the sound blast aimed back at me and to each side was intense! So, with ringing ears (even using ear-muffs) I looked for a good linear comp to direct that blast downrange and away, and it does just that.
Until I finally install a can, (with the 7-month ATF wait time) this is a great alternative, and it saves my ears. The Helios-K has a very fine finish on its titanium construction. As others have mentioned, very easy to install and tune.
