Yes. It's for real.
I've taken XS drum mag for AR-10 (in .308) and shaved off a bit from the sides

There were:
1. minor problem with internal spring (which pushes movable lip) but it was solved.
2. Issue with rem700 reciever getting in the way - it also was solved by removing bits of material in the points of contact

I think this pic is self-explanatory:

XS drum mag has single-stack feed by design so obviously it was just a question of fitting it inside AICS triggerguard. Luck also helped a bit

Oh yeah...I remember that thread now. I suppose if a competition necessitates it, then so be it. Looks like some pretty handy machining work.

Out of curiosity, will the magazine still fit/function in its original AR-10 host?

I was laughing my ass off from this post!

What does that 50rd mag weigh in at, all loaded up?

Well it was fun project. I'd prefer pmag with 20 rounds in it... but unfortunately it's almost impossible to install double stacker .308 inside rem700 without machining an action.

Mag itself weigh s 1.5lbs empty... add 50 rounds and you're there.

That is damn cool though. Well done!

This magazine was made just for the stages with more than 20 shots.

Ok I dont mean to be rude but Do you really live in Moscow? You are allowed to have this stuff there? They have IPSC there?? Im not tryin to be an ass. You have captured my curiosity. Or are you kidding about your location?

1. Yes I live in Moscow, Russia (heart of Evil Empire)
2. Yes we have IPSC here. (You can check ipsc.org for calendar and will find Moscow Open level III which was held not long ago http://ipsc.org/matches/calendar.php)
3. Yes, we allowed to have stuff like that (with some kind of restrictions - I can use this magazine only at competitions)

Yes, for defending the Motherland against the Nazi aggressor swine.
 
It's been a long time since this was originally posted... does anyone know if there is a commercially available AICS-compatible drum mag with 20rounds or more?
 
PMAG D-50 fits in a RPR. I've considered getting one just for the giggles at a match. The local match MD has been incorporating a "no round count" stage recently that I'd love to use it in. If my recollection is correct, the stage is cleanable in 6 shots.
 
Nope. Biggest thing I have seen is ~14-16 rounds with a baseplate extension.
If your rifle will accept a SR25 mag, a magpul 25 round M118LR mag with a Taran Tactical 5 round extension will get you to 30, though you'll need to do a bit of sanding on the internals to get it to feed all 30...
