What kind of flash hider should I choose?

As cool as they may look, don't get anything sharp. As mentioned above you can seriously hurt someone if your not careful and even if you are. I personally have had someone I was flanking turn and run around a corner right into me, we both fell and he landed on my muzzle like a punji spike- full body weight. Fortunately I just had a regular birdcage on mine. If I'd had something sharp on the front of mine he'd be less a kidney right now and I'd probably have a room mate named Bubba. There's a reason that they put rubber bayonets on airsoft AKs'. Personally if someone opened me up with one of those things, he be making a trip to the dentist afterwards.

Thanks for the stories guys, I think I'll stick with something simple then. :P
