Has Colt chosen the MWG 90 round magazine for the IAR?

For a while I have been waiting for Colt to a announce a ultra-reliable ultra-high capacity magazine that will accompany the Colt Infantry Automatic Rifle. One of the requirements for the Marine IAR is a ultra-high capacity magazine.

At the Pakistan IDEAS-2008 expo an M16/M203 was on display with a MWG 90 Rounder High Capacity Magazine, sitting directly above a Colt IAR poster (Photo by skybolt @ Defence.pk).

The tan colored weapon on the poster is the Colt IAR. Click to expand.

I think it would be safe to assume that Colt is going with the MWG 90.

MWG 90 Rounder High Capacity Magazine

If you look closely at the first image it appears that the MWG 90 magazine is attached to the M16 upper receiver. Something is attached to the receiver which extends towards the magazine. Anyone know what this is? It does not appear visible on MWG promotional photos, such as this one:

Colt may have customized the MWG 90 to increase reliability/durability.

    Lancer 48 rounds can only be loaded full if you insert them with the bolt locked back. Otherwise you have to download them to 47

    I agree with Wayne USMC...

    I have used the Surefire 4-stack magazines plenty of times, and I now own 3x 60rd versions. They are fantastic, and the 60rd magazine trumps a 100rd Beta any day.

    I have used them in my HK416 (C-III) and a couple RRA AR-15/M4-style weapons. They have feed issues about twice as often as regular magazines (well, I use EMAG's) and certainly add some bulk to the bottom of the weapon, but they are easily handled, no wider than the widest part of the receiver, and give double the ammunition.

    I have fired through all 60rds in one full-auto burst and it's impressive, as it turns the full-auto setting into something actually useful, rather than keeping it essentially a "burst" mode.

    I do think this new magazine looks interesting, but I cannot see it being practical due to, well, everything that has already been stated.

    The only use I can see for it would be for the person carrying the IAR, to keep 2-3 of them in pouches without sacrificing any of their traditional 30rd magazines. If they are in a position to be laying down a lot of lead, switch to the 90rd CMAG, and if not, use the regular mags.
