Armatac quad-stack magazine

[MFC Bastion]

Long time lurker, first time poster. Apologies if this has been posted before, I searched but couldn't find anything.

Armatac, the makers of an obscenely expensive 150rd drum magazine for the AR, show a developmental quad stack 50rd box magazine on their website: http://www.armatac.com/VIDEO/quad50.jpg

Kinda like the 60 round quad stack AK mag we've seen occasionally. Or the Spectre mag. Wasn't LWRC working on one of these?

What do you think? How reliable could something like this be in real life?

Exercise in futility or absurdity? You be the judge.

So, based on their current rates, it should cost around $600 or so, right? That means, $10 per round or capacity! Even the best 30 round magazine doesn't cost more than about $2 a round.

Why? As much trouble as the world is having making a double-contour (curved on the bottom, straight at top) magazine reliably feed, why would ANYBODY add another element of unreliability to the equation? It can't be any more or less reliable than the Betas, but at nearly half the capacity and sticking out farther than a 30-rounder? Why not a 45-round double column?

I'm going to second that, Badger. While there's nothing wrong in principle with a quadruple column magazine (as MFC Bastion points out, it's been done before), the perverse curiosities of the AR-15 magazine well mean that anything that's going to fit into it will have to be unusually thin, and straight at the top. Enough trouble as is getting the two column magazines to work!

yep, but just think, years ago when they first came out with double stack magazines, they were unreliable. now today they are the standard.

you gotta give these guys credit for thinking outside of the box.

too bad, anybody know if some company makes 100 round drums for 10/22s, that would be pretty cool.
