I always thought there was some kind of legal issue with having LAR-10 mags with full 10rd bodies. Something like how the originals got approved in only 10rd bodies, and 10/30 mags are considered a "modified" 30rd mag and not a 10rd "pistol" LAR mag. I know it sounds stupid but I've seen the idea repeated enough that I always thought 10/30rds wasn't legal. There were a few companies in the past that did it and they were getting called out for it, it probably didn't help that they were pretty sketchy overall.


Thoughts?
