I would also like a link to the manfacturers site please.  I know there was a discussion on this a while ago but I can't find it now.

Thanks

The Vortex

SEARCH for it my friend. This question comes up all the time.I just did a search and this very same question was asked very recently. The thread even had a poll. No need to rehash the same old, same sold, eh?

Only two to choose from... Vortex and Phantom.  If an A2 get rid of 75% of the flash a Phantom gets rid of 98% and the Vortex 99% of it.  Vorxtex weighs a bit over 3oz the Phantom 2.1oz, the Vortex makes a tuning fork ring when you shoot the Phantom does not, The Phantom comes in closed bottom and symetrical versions with the closed bottom requiring timing by a crush or peel washer, the Vortex does not need to be timed and does not use a washer. The Phantom is $25 and the Vortex $50. YHM and AAC are using Phantoms as the foundation for a suppressor mount and teh Vortex takes a suppressor noone seems to be able to get that is a civilian.  Either flash suppressor works with RD Systems suppressor.  Vortex claims an accuracy increase but that is vs. an A2 and a Phantom will still let you shoot way sub MOA so accuarcy is a non issue.  Vortex seems to be more popular by a small margin right now.  I decided to go with a Phantom on my current build simply due to my personal dislike for the extra weight of a Vortex and the ring it makes.

I would always go with a vortex if I had the choice but with suppressors you don't, a few are becomming compatible with Phantom systems, and only one very high priced Arms tech product uses the Vortex.  

They really do enhance accuracy-- I think it is both the cutting of turbulence imparted to the bullet and the fact that you don't need to tighten them and they still stay on the muzzle [tightening a muzzle attachment is detrimental to accuracy].  

I'm beginning to see the phantom as a better option than before but still prefer the Vortex G6A2.
