I seriously thought about this one, but I liked the way this one looked better:
There were many I had to discard because I needed one at least 2.5" long to meet overall length requirements.
The device in the picture is the Precision Armament Enhanced Flash Arresting Brake (EFAB). It's supposed to be the pinnacle of...whatever, they all say that.
So far, it's been great. My gun already had little muzzle rise and this reduces it to zero. The .223Rem/5.56 NATO is already a light recoiling round and this brings recoil down to very light.
Like I said earlier, I looked closely at the Lantac Dragon. The Dragon is probably better at recoil reduction (which I don't really need), but it's a terrible flash hider. I haven't fired it in the dark yet, but all reports say the EFAB hides flash almost as good as the A2 flash hider which is pretty good.
So, the combination of performance in all areas and the fact that I like the looks, this one won out. It was more expensive though.
