You serious? I thought it could. Why oh why does that whole fiasco smell of H&K trying to snuggle their 416 platform in to replace the M4?
Yeah dude, they made a 100% STANAG magwell. Don't know if EMAGs will work or not but PMAGs and the SF mags are definitely out. Rumor has it SF is redesigning theirs to work with the IAR but that's just a rumor.
