I asked for a release date on another forum and was informed that it will be available by mid-December ( I was typing this as FPemblton posted)!.
I'm liking this item but I would want to run one to see for myself what the benefits and downfalls are. From a number of pics that I have seen of it in use, it looks like it allows a better grip on the fore-end when using the thumb-over grip.
As Jamie said, I can see it hanging up less in a vehicle or on equipment (my current verticle grip has), it can be used through gun ports, and is slightly more compact. And, as Greentips pointed out, it does take up a ton of rail space but I don't think it is something you would mount on an SBR or support weapon and it is obviously more suitable for those who run a light at any poistion other than 7, 6 or 5 o'clock. Heck, in Canada, most people mount a light but never turn it on (Mil and LEO's excluded)! I run my light at 9 o'clock but far forward on a tri-rail (I need that Mk 18 RAS!) and with this grip I think I could still easily reach the end switch.
It looks very suitable to a CQB, tactical or competitive firearm by allowing the shooter to drive the gun a bit faster.
They have done a good R&D and have produced a very informative power-point comparison regarding various grips and holds.
In the end, it will come down to personal preference but I'm going to grab one and wring it out so I can see for myself.
