Magpul Quadstack Magazine - patent filed

Why? Another happy meal toy from Magpul...

What kind of teething problems did the AK74 quads have? Were they a similar design? Glancing at the patent (with all my years of mechanical training I received with my liberal arts degree) it looks like those spring-loaded bails might be susceptible to getting clogged up with debris.

They had durability problems and started having reliability problems with age (springs maybe?). I wouldn't expect either from Magpul. Not sure if the Ruskies got theirs sorted out. Its been since I've looked and info is hard to come by. One advantage the 74 quad has over an AR15 quad is the 74 mag is able to stay quad stack almost all the way to the top due to a lack of mag well.

If it's close, does the US Patent Office grant patents to a design that's very similar to something that's already been released somewhere else in the world? (The EU patent office does not IIRC)

74 mag is a bit different. Even if they were filled to the same office I would guess each would get their own patent.

What are the other happy meal toys you're referencing?

Cool. There was an Italian 9mm SMG that used a similar type magazine back in the 80's. Spectre M4. http://en.wikipedia.org/wiki/Spectre_M4

The AK-200 will be coming with 60 round quad stacked mags. They have been demoed and appear to have all the problems worked out.

That would be a Spectre M4.

Just found it on wikipedia and did an edit to my post.

Versus 30- and 40-round mags of any make and those 3000 Miles to Graceland snail-drum abortions as an ammo source for the IAR? Not only yeah, but f**k yeah, it's got merit.

Are you suggesting a viable alternative? Because if you're not, what's to distinguish your above from all of your oher nigh-unsupportable snarking from behind a screen-name because you think it's cool?

We get it. If it's not from Colt, you don't like it. If it's Magpul, it's not Colt, so you don't like it. Get a new gimmick, already, or at least use the shoddy one you have to submit something with meat on it's bones.

I REALLY hope this works as well as the P-MAG. This would be perfect for home defense usage on standby. 50 rounds of GTFO on hand w/out a mag coupler or redi-mag.

Do you have any idea what it would cost to fix the drywall after letting loose with that?
