WOW! This sure took on a life of it's own!
Seemingly there are several here who would rather toss out a worn mag than try to have a bit of fun making something different....Lighten up, guys!

My intent was merely to ask if anyone else has done this and what they did to accomplish said task, but I really got a load of sarcasm!! Lucky I have a sense of humor (I really was laughing at some of the relpies!!) Belt fed....Hmmmmmm!!!
Anyway, I've seen these letters and references from Bardwell (Small Arms Review) and on Subguns.com and there is nothing illegal about this....no more illegal than grinding off a bit of the front pad on a Swede K mag so it'll fit my S&W 76. Phil wins first prize....this is legal, but building a drum from parts not yet assembled before Sept. 94 is not. I'm not worried that the BATFE

is gonna knock my door down for inquiring about something that's been documented as "OK" with them
Anyway, some of you guys gotta realize that some of us just like to experiment. I don't really have too much time on my hands....wish it were the case!!!
And I'm not talking about destroying pristine 30-round pieces of living history here, either.....these mags are dogs that won't hold rounds....they're that worn!!
Anyway, keep up the good work, folks! I ain't laughed this hard since the hogs ate my little brother!!!!
AND.....if anyone has more to say, pro or con, go for it!!
I'm on a streak, folks! This is a record for me on number of replies for a post....my personal best!!!
