    I've read that drums don't play well with these without cutting up the magwell, and I don't plan on doing that. That said, are there any 20/30/40 rounders that don't work well with the 556Rs that I should stay away from? Especially interested in picking up a couple 20 and 40 rounders that are good to go, but don't have enough experience with this caliber in general.

    Any info would be appreciated!

    I like KCI 20rd Tanker Mags. No clue on the drums always avoided for same reasons mentioned above.

    I have a Gen-2 556R. EVERY magazine I’ve used had to be modified to fit the magwell. I emailed Magpul about it and the reply I got said that their magazines fir the 556R that they had. They told me to file off the rear lug as needed off the mags.
