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.

MD Arms have just started shipping their new 20 round drum magazines for the Siaga 12 shotgun. They cost $215 (+ $3 handling fee).

It look like they have only made enough to satisfy pre-orders and are now taking pre-orders for the second batch.

The Unforgiving Minute has a post on the dangers of magazine safeties.

Referring to the SR9:

It is the worst of the worst! With the magazine removed, the trigger functions normally, dropping the hammer, but the gun is prevented from firing. (…) It simply blocks the firing pin! Upon hearing a “click,” instead of a “bang,” the shooter knows little, because the pistol has told him little. Chamber might be empty. Might be a dud round. Magazine may be unlocked.

Being a Glock fan, I personally think the less external safeties the better. As mentioned in the article, a magazine safety should not be the only thing that separates your kid from firing your pistols.

From Army Times

One of the upgrades that may be coming in the future is a more reliable magazine. The test revealed that 239 of the 882 stoppages M4 suffered were magazine-related.

The hope is that upgrades, such as stronger springs, will increase the magazine’s ability to feed rounds more effectively, Radcliffe said. If all goes well in testing, the improved magazines could be ready by next spring.

Another upgrade under consideration is a “hammer-forged” barrel, Brown said.

I didn’t think that they were actually planning on replacing the M4 when they announced the testing. Even without magazine stoppages the M4 performed very badly.

DID has a very comprehensive article

“Even with extreme dust test III’s 98.6 percent success rate there was a total of 863 class 1 and 2 weapon/magazine stoppages with 19 class 3 stoppages. During extreme dust test II conducted during the summer, there were 296 total class 1 and 2 stoppages and 11 class 3 stoppages.

A class 1 stoppage is one a Soldier can clear within 10 seconds; a class 2 stoppage is one a Soldier can clear, but requires more than 10 seconds; and, class 3 is a stoppage that requires an armorer to clear.”

DID will simply point out that 10 seconds can be a rather fatally long time when people are shooting at you, and at your friends. So, what happens when the Extreme Dust Test III stoppages are broken out by weapon?

The M4 Carbine is the Army’s existing weapon.

* 882 jams, 1 jam every 68 rounds, again using heavy lubrication. In addition all 10 of the M4 barrels needed to be replaced, and a number of their parts were replaced during the test. None of the cold hammer forged HK416 and XM-8 barrels needed replacement.

The HK416 is a modified M4 carbine, which can be and has been converted from existing rifles. Used by US Special Forces.

* 233 jams, 1 jam every 257 rounds, 3.77x more reliable than the M4.

FN SCAR is US special Forces’ new weapon, designed by SOSOCM. It just went into production in late 2007.

* 226 jams, 1 jam every 265 rounds, 3.85x more reliable than the M4

XM-8 is a developmental rifle. It’s an advanced version of HK’s G36, a rifle in wide use by many NATO armies. The US Army cancelled the XM-8 weapons family 2 years ago.

* 127 jams, I jam every 472 rounds, 6.95x more reliable than the M4.

Hat Tip: Murdoc Online

Very cool! But it weights 6.5 Lbs / 2.95 kg when loaded!

Of course if it is not reliable then it is just dead weight!
